Now that they did some black friday deals on S4, I am pretty sure once S4 is sold out they will announce S5.

What black friday deals?

there was a scam site which robbed people, offering massive bitmain discounts. perhaps that news hasn't filtered through to some yet.

This is true, but they are also selling S4s for 30% off and free international shipping, but you need to buy at least (I think it is) 16. Even with those prices the difficulty will need to rise very slowly for you to potentially ROI.

All this S5 speculation on ONE advert on the net ... placed weeks ago ... and not verified by anyone?

Sit back, relax and enjoy the ride ...

Yes the S5 (or whatever it will be called) will arrive, at some stage.

Well, in reality that "black friday" sale was announced on Saturday and it is ONLY if you are getting 16 S4 units, not for a single unit.
However, ALL coupons were extended to 12/15, so there is a discount.

I think, according to what members say that they receive i used S4 gears full of dust, and also the huge sale that bitmain need to do with the current products. this only mean that they replace their farm gears with some thing more powerful and they need to sell all the old stock.
May be after a while when they use this new product and get some decent profit from it then they will release it to the public.

i've a feeling that doing this is going to put a stop to the cogs. While other h/w manufacturers are shipping more efficient miners from stock, do you really think bitmain would halt sending out their most profitable rigs to customers and let other companies take the market share.

and just because they can mine themselves with their new gear, does this not mean they will be stuck in the same position when they do open it for sale? other manufacturers will be a jump ahead.

my opinion is that S5 isn't finished yet and as soon as it is, they will want it out on sale to customers.

I actually prefer them to sell used S4 miners but for cheap, price is more important then new or used right?

I just received an S4 yesterday from Bitmain and it was brand new, opened it up to verify nothing unseated from the flight and it was brand new inside as far as I can tell. Either it is brand new or it's never been scratched and they blew it out really good from when it was used last

What is your point, Speedster?  Don't think I'm being sarcastic because I'm not.  I'm just trying to figure out your point.

They probably used the S4 before starting selling them but they sell new ones.
It will be interesting to buy new equipment when we can expect not to have far better equipment coming out in the near future. We will be able to mine the equipment with a stable difficulty.

at what level of difficulty do you suspect we will have reached by that time?
could be close to 100billion if price rises alongwith?

They might use 16nm chip for S5 and push down the watt per gh/s down to like 0.2.

If they use 14nm/16NM FinFet then we won't have to deal with those swedish KnC Fudges, or risk having the building torched by some super heated Spondoolies Tech rig.

I don't think you can blame SP for the building fire.... they build a quality product.   

And I would wait on bitmain vs ever using KnC. 

[huffdaddy5]

If i had to speculate, I would guess they will go with a 20nm technology. I don't even know if Hashcoins is legit, but they are announcing a January 2015 release of the "Uranus" which promises 6TH/s @ 1600W (0.26W/GH) using 20nm technology.

I found this miner on this wiki that is not completely up to date..

IMO this is too soon for that. It may be likelier that this is just a revised 28nm design, such as using larger cores or multi-cored subrates (like a hashfast chip). This sort of redesign would allow for small changes to improve where unexpected losses were seen in gen1. (similar to the asicminer BE300 being an improved 28nm design on the 28nm BE200)

If i had to guess, a 0.3w (power-saving mode) to 0.5w (turbo mode) chip is likely. Alternatively, the S5 might just use more of the 28nm chip undervolted slightly inside an S3-sized enclosure; similar to how the S4 uses 5xS3 worth of chips, but all undervolted slightly for a ~0.1w/GH improvement on power use (ie: down to 0.6-0.7w/GH to compete with the spondoolies Sp20)

Amen to that!

Well they are obviously not going to launch on the 15th of November so maybe the project changed when they saw what the competition are working with. I agree, however, that if they release it within the next month it is unlikely to be 14nm/16nm FinFet. I really hope they stick to many smaller chips rather than fewer larger chips. The larger chips are more difficult to make power efficient, to cool, and when one is wonky the performance drop is substantial.
