why can't they release both together? I want the PS4 version
I honestly don't think they've even begun to port it to the PS4 yet. Who knows how much they have to do for the PS3 release; it's coming in like 5-6 months, so they might still have some semi-major work left to do. I think they're going to gauge sales, and if they see it as a big success like Heavy Rain we will get a PS4 port later on in 2014.
