@darkknight: sorry mate :( i don't know that information..all I have seen about the vita version is that, it looks great, plays great, can be used as a ps3 controller for the game etc. If I find out info I'll post it here (if you find out do the same so others will know)
also I have been reading user comments over at gaf and it seems many are actually quite happy with battery life :D don't think i saw a single person not satisfied with it..someone actually said of an instance of Golden Abyss with wifi on for 5hours +..sounds pretty good to me! many of them are saying its around 3ds battery life or better
and I'm pretty sure this trailer is new..Shinobido 2!
