Vita is also getting tales games... so there IS that as well.
We get a PS2 port in Tales of the Abyss.
I got to play the greatest tales game in Symphonia, but sadly that is it. I need to get more.
The Vita has some great games, I'm sure and you honestly can't go wrong with either.
The 3D feature was a cool idea, but just doesn't work out all that well in the end. I do turn it on to watch cut scenes and they look really nice, but that is about it.
