Aw - thanks :D
Hi, Kirsty from FuturLab here, thought you'd appreciate an update on the Vita situation. SCEA currently have a backlog of PSP content that they need to approve for Vita. Apparently Velocity is high priority in their approval list so you should all be able to play it on Vita very soon (because it plays THE BEST on Vita). I'll post an update when I have a date or know more.
Glad you're enjoying the game and thanks for an amazing review ZTGD!
