I don't know about the others, but apparently Ys MoC is a lot closer to Ys Seven than the other games in the series (Origin, Oath, Ark). I'd still get Ys because it's the only one I know from your list :3

Ys! Best game out for the Vita right now.

Wait for the FFX and FFX-2 HD!

Hmmm... well this year should be good for all ps vita owners.
