Just another reason why I own a PS4....for exclusive games and games that will take a long time to come out for other platforms.
Like @fedor stated above, They are under NDA and SE is simply saying that they're focused on getting the PS4 versions done before focusing on getting the games on other platform is what's applying here. And if you look at the trailers saying "coming first to PS4" rather than "exclusively on PS4" is very telling that its likely going to be on at least one other platform. It'll end up on PC & possibly on Xbox One. (Or Scarlet)
I agree, I think it'll end on PC at least. But I still have to wonder how much sony is paying them. Everyone knows this game is THE REMAKE everyone has been asking for more than 10 years.
Just like with SFV, it did well for both on PS4 & PC, so it all turn out well for both platform. I also like to see FFVII Remake coming to Switch at the very least but other then that, PS4/PC should be good enough.
