The PS4 will not play PS3, PS2, or PSX games, this is a failure in my eyes from the get go. PS2 is as far as I go with Sony, The new XboX has not confirmed the backwards compatibility but you can probably bet certain titles will be like gears of war and halo etc. which is a little bit better. Nintendo has it in the bag, All Wii games aside from a few are playable on the Wii U, the only draw back is that Gamecube is still left to your old Wii console or the actual GameCube. It is all Apples, Oranges and a Banana I guess. I just think Nintendo will come out ahead big time in this generation.
