it's possible ... huge games next year like Smash and Mario Kart, and smaller ones that will have a combination effect. i wouldn't buy a Wii U for Bayonetta 2 for instance, but Bayo 2 + Yoshi and Donkey Kong is quite enticing, But .... eh might not lulz
Playstation = The Beast from the East
Sony + Nintendo = WIN! PS3 + PSV + PS4 + Wii U + 3DS
