God Eater could be a big deal for the Vita, bringing over a million potential fans over from the PSP version (although since it is coming out on the older handheld too, perhaps they won't bother). Still, with cross play between the games, it makes a good crossing route to the Vita and between this and Soul Sacrifice, Japanese gamers can get their fill of demon slaying.
As launch nears, Namco has out a couple of awesome new videos (below), showing off the recently unveiled weapons and some pretty chunky monsters getting mashed. Crank the videos up to 720p for the best view. Everyone start praying for a western release.
