I think it will have some software backwards compatibility (think Xbox -> Xbox 360) or maybe a streaming service like PSNow. 3DS games will definitely be playable, Wii games should be playable (Wii emulation isn't hard), Wii U games - maybe/maybe not. Nintendo could always support the game-pad for previous Wii U owners who don't want multiple systems taking up living room space.
