Again and again and again.
As far as I'm concerned PSVITA begs for some episodic content from all the big franchises.
New and short stories with reused assets from the big sisters versions.
Or they just put Bayonetta and Vanquish on it.
One of the reasons that made me preorder was the NGS+ announcement (and Gravity Daze/Rush). I have it for the PS3 but I want play it without having to use the TV in the living room. While others watch TV, I can play the game.
I just hope they implement a save anywhere and anytime feature. That would make it much more feasible as a handheld game.
Bayonetta and Vanquish would be awesome on it. That's what appeals to me about the Vita. It can have both full console, lengthy experiences like Batman AA/AC that I prefer and more bite size, episodic, portable experiences that fit other peoples preferences.
EDIT: And I am stoked to play Persona 4 The Golden on it. Watched some of the GB ER and liked it but didn't feel compelled to play it on a console. When I saw it announced for the Vita, it felt like the perfect platform for me to experience it.
