Except in this example, using the Vita seems to only be for specific levels where the Vita player needs to help the other players.
But hey, people keep bringing up Wii U, not seeming to remember Gameboy Advance with the Gamecube, Dreamcast, and I'm positive there's some other things floating around.
Oh, and by judging from the PS3 and the PSP, it already looked like Sony was trying to incorporate their handhelds with the systems. They just abandoned the PSP and made the Vita at the wrong time.
Oh, and I guess we could all call on the Wii U for being a ripoff of other consoles for being HD. Who cares what we find fun in a console? We just want them to be original!
