The only thing you are right about is gaming devs will put money into the biggest individual platforms and for now that is the PC.
Also if consoles do more and more PC type things because of hardware changes eventually they will evolve into PCs.
TBF the PS4 and xbox one are practically PCs from gaming software production POV, the main difference, they can optimise for a limited number of models.
And I'm sure we've seen a lot more PC conversions as a result. Particularly Japanese RPGs which used to be console exclusives are coming out on PC, some even on launch day.
