What kind of adjustment do you mean? Block size halving (August 2016) is still too far away for miners. I'd say only hardware producers are pretty aware of it ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Also on a sidenote the S5 ships Dec 27th. Will be interesting to see effect of that on hash rate.

Estimated Next Difficulty: 37,460,709,208 (-5.06%) WAW! ![Shocked](https://bitcointalk.org/Smileys/default/shocked.gif) Keep in mind that this is based on the last X blocks - not sure how big X is but quite sure at this moment it still includes the peak of XPY mining. This will fall off in a few days, so there is going to be bump up, question is - how much exactly. I believe it is 504 or ¼ of the 2016 in the adjustment. If so We still had pressure up to sat so 3 days after sat is tues. We should see big gains well 2-4 % and since we are 4.5% neg we may get back to -1% by late tues or early weds. we will surge up in the next 3 days for sure for reason that OP posted (burn in), so you are right, we might get to par or -1%. next one will be at least +3-5%

The XPY machines most should have made it back by now. There are some chances are still on rental sites and nicehash still, but most should be back soon (If not already it's been days since XPY gave rewards for mining). I would not say to late. In 5 days they ship. We will see testing (burn-in's) prior to that. It's safe to say we will see a increase in hash rate. We cannot predict what that is. But expect something to be replacing those old Dragons, etc. Most have cheap electricity, and not shut down. It could be SP gear, or Bitmain. The advantage with SP would be something like sp-35 you get around 5T per and are all ready for rack mount. I don't know if it will be enough to go positive or not this round but it will go up some.

I would say -2% should be OK for the next diff. S5 seems again a bit high in price but ppl will buy it anyways XPY mining has ended a couple of days a go so whoever wanted to come back is already back. Most likely some S1s and other old is now completely off after the XPY rental boom

they burn in S5 before shipping-my take, which makes it ~20-30PH of S5=15-20K machines ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) ?

I would agree I think most are already back from paycoin. I think we will see quite a bit of S5 burn in. They seem to sell quite a few each release. With this being a new chip a lot will probley buy.

Honestly I don't see the S5 making that big a difference. It really is too late when you compare it against the competition. Now that we know the S5 specs and price, it doesn't seem all that compelling.
For example, if I'm reading it right the S5 has no DC/DC converters which means that programable over or under clocking is out of the question for most users with standard power supplies. Also, it sounds like if there's a single ASIC failure in the chain, the whole chain falls over.
While all of this adds up to cheaper construction and better profits for Bitmain, it means the S5 is less flexible and likely has lower resale value potential than the competitors like the SP20. If you can't effectively under clock an S5, then what value will it have a few months from now?
Add in the fact that the free review models of SP20's have resulted in enormous PR on this forum. Those SP marketing folks really know how to effectively schmooze. Bitmain's PR and communication skills just don't compare.
Sure, some people will buy the S5. People like Bitmain and they like shiny new things, and they will buy it without doing their homework.
But it's not going to be a game changer for the next (or any) difficulty adjustment.
I'd be more worried that Spondoolies reduces the SP20 price again. If they knocked off another $200 (unlikely, but who knows), and if they could build them fast enough, they might move enough units to propel the difficulty again.
Hell, I'd probably buy more and have no idea where I'd put them (they are loud!)

^1 in a chain failing will almost certainly have no effect - the chain is only new in the way it divides voltage across chips, and the chip design should still act as a load even if the chip is disabled. Unlikely to be a major failure
^2 the s5 could more easily be undervolted by adding additional chips of some other form of voltage drop to the series circuit. If bitmain was smart they would incorporate some sort of toggle/dummy-load or make an easy way to plug a 3-chip module onto the board to effectively knock down the voltage/chip to improve efficiency down the road

the battle looks to start between the s5 and the sp20. 1) the sp20 is now in a group buy 2 for 1000 2) the s5 dropped from 450 to 418 3) I have been offered a free demo s5 from bitmain for me to do a review on it. I said yes and will post a review when the time come. I will take the s-5 and do a stand alone review . Next I will try to do a fair compare between the s-5 and sp20. Now I know a lot of people will think hashrate will move high due to this. well this gear is going to make all gear over .8 pretty much unless. and even s-3's will not be too good unless you have really good power prices.

difficulty is getting so HIIIGH now with the new S5 !!! you might have to rethink your plans with only 4 % diff increase ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif) Longterm diff calcs are really hard. Last summer I joined the camp that thought diff was going to slow a lot. It has. I do not know if 4% for the next 6 months is right or wrong. it is possible. If the sp20 the sp31 the sp 35 all do .5 watts If the s-5 does .53 watts. They will make the s-3 worth very little. So a lot of the s-3's will go off line. S-4's will stick a round longer. Thus a limiting factor to new growth is 50ph of the network has to be in s-3's soon they stop making money. At 4% 326 usd a coin and 10 cent power an s-3 makes 3 dollars a month in Aug 2015. At 15 cents it makes 2 dollars a month by April 2015. So the s-3 will be at end of useful life in the spring of 2015 for some of us and by the summer of 2015 it will be at end of life for most owners of it. They come off line diff gets downward pressure. Of course if price jumps to 600 usd all of the above is wrong and diff will jump faster. today we are at (-3.68%)About 7.2 days to go https://bitcoinwisdom.com/bitcoin/difficultyprice is 326 usd
