Meaning loads since as far as I remember, the Kinect was pretty succesful. I remind you that this is not a PSP Remote Play sort of deal - all PlayStation 4 games will be streamable to the PSVita unless they use the PlayStation Eye. I get your point though, nobody's going to get a PSVita just for Remote Play, but there are other factors in play here, for example Instant Game Collection.
Just chiming in, but Kinect probably only did well, because it was bundled with the console (Not trying to argue any points, just randomly stating this). Also, I bought my Vita just for remote play (I was disappointed).
Also, I'm late, but earlier there was something about Monster Hunter and Xenoblade controls. As a player of both, Xenoblade played fine and Monster Hunter plays like poop no matter what kind of controller you have (The contents of the game make-up for it though).
On-Topic: Original poster, Definitely look at an upcoming games list (as I find it hard to believe you only wish to play Mario-like platformers forever) for each console. For now, I think Wii U is your best option. My PS4 and Xbox One are collecting dust right now, because the launch titles I got them for aren't launch titles anymore (Infamous ans Watch Dogs for PS4, Titanfall (I don't think this was ever a launch title) and Killer Instinct, which wasn't delayed, but I didn't care for it for Xbox One). Although, there are lots of great games upcoming for all.

Also, whoever said Ratchet and Clank, Sly Cooper, Jak and Daxter, etc. is like Mario, I disagree. While all of the former feel similar in gameplay fashion to each other (In my opinion), they feel quite different from Mario. LittleBig Planet was a closer comparison though (even if the actual platforming isn't particularly interesting or fleshed-out in my opinion).
And... Done playing catch-up. Phew!
