The block reward won't change after august 1 but it's unpredictable what will happen with the difficulty.
Your earning won't stay the same, I guess that differs from day to day, isn't it?
So the block reward will be the same, but the diff rate will decrease? that will let miners get more BTC?
Is that good or bad generally? and specially on BTC price - i guess the price will drop for a while.
That's correct, if the difficulty decreases you earn more Bitcoin.
Although you can't predict exactly what will happen.
I guess the price will drop, also because BTC-E is probably hacked.
Most of the time the difficulty drops then, so you make more BTC but it's valued less in US Dollars.
