There's a handful of games that would suffer more than others from the transition to the 7th gen (for various reasons), but past that the majority of PS4 and X1 games would be entirely possible on the 360 and PS3. Sames goes for the WiiU and Wii (ignoring the Upad, which i don't personally think Nintendo have justified yet anyway).
There are some upcoming games that look genuinely 'next-gen' relative to their predecessor (XCX and TW3 being some good examples), but i can't think of any present releases.
