I would quit console gaming if they go full steam machine model too.
But I don't think this is the case, yet.
I think this is Sony making PS4 slim and found out that they can put a little more transistors into the chip at low cost so they try to capitalize it, which I'm somewhat ok with.
As long as I still get my true full generation leap PS5 without PS4 Neo holding back.
I dont think they are done with numerical values at all. PS5 will be for the next "minimum standard jump". it'll probably just come a few more years later than it would have if PS4K didn't exist.
And i also agree with you about this probably coming about because of 16nm's dividends for them
