When ASIC reach a cheaper point and everyone can get one then theres next step in BTC. But the Difficult will only increase, pretty similar to the jump CPU>GPU mining.

Right now GPU miner won't drop, if they do the difficult would go down and GPU miner who don't drop will have more BTC.

When GPU miners drop out of the network en masse, their cumulative hash power will likely be a drop in the bucket in comparison to the widespread ASICs, so difficulty won't drop enough for much of a change in profitability for lingering GPU miners.

I do agree, however, that we will see a similar type of shift as you point out with CPU>GPU mining. With the only difference, and certainly a considerable difference, being that the ASICs aren't as easily re-purposed and sold (if at all) for recuperative costs. All profits are left up to the performance the ASIC had earned.
