I think it's definatly possible. Given RE had a substantial fanbase on the original Playstation there could be a lot of PS3 only owners looking forward to this game.
Me I won't be buying this one. I haven't finished 4 as is, but this one seems to be ridiculous. Also, My budget is flatlined at the moment... I will eventually play the demo and see what I think of it.
