For me the problem wasn't "no game" but no exclusives. I have a PS3, a Wii and a 3DS...of the games in the op, there are only 5 (i think) that I can't play any where else or that I can't play their superior counterparts elsewhere.
To clarify, there are games like Rayman Origins which I can just play on my PS3 if I want to (with the benefit of my big screen TV and local co op using one console). Additionally, there are games like uncharted which I can just play the superior 3 games on my PS3 if I want to...
The games on that list that don't fit into the above categories are: Tearaway, Gravity Rush, Toukiden, Ys and Danganronpa. Of those, I really only care about Tearaway and Gravity Rush
...so yeah, thats my opinion on the matter. Vita has some great games, I wouldn't argue that, they just aren't games that compel me to buy the hardware...
EDIT: I forgot about Persona 4 because it was on the PS2 but you can add that to the "games I care about" list
