Earth Defense Force for Vita coming next year

Earth Defense Force Portable 2017, a Vita version of the Xbox 360's EDF 2017, has been confirmed for North American release. The game is vaguely set for "winter 2013," which probably means sometime in the first quarter of next year.

D3Publisher tweeted the news (via IGN) with a lone screenshot. The game was first announced a few weeks ago at the Tokyo Games Show, but D3 hadn't confirmed a domestic release until today.
