Yeah, It's one of the rare Tecmo vita successes. it ran pretty good from the earlier footage too, but I'm still not sure if I'll be getting it though since i didn't even finish the first game.
So, Toukiden 2 was delayed a month. Hopefully this means they are taking some time to better optimize the vita version. Demo should be out in a couple of days so we'll get to see how bad/good it is at its current form.
