Square-Enix is pretty good about releasing PC versions, usually through Steam... but only of games made by their international studios. Their Japanese games have a tendency to be exclusive to consoles.
It's a shame really. I personally prefer PC versions unless there's something clearly wrong with the port (RE4). My monitor is higher resolution than my TV, my PC is far more powerful than my PS3, and Steam is far better about updating games than the PS3, which will wait until you want to play. Not to say that there will be anything wrong with the PS3/Vita versions, I fully expect them to be competent ports. But as long as they're only on consoles, it's merely a probably buy for me. A halfway-decent PC version would get a definite purchase out of me, possibly even a preorder.
