3DS sh'mup Kokuga, which comes from the same brain as Ikaruga and Radiant Silvergun, has finally been confirmed for western release.
An English site for the shooter popped up on G.Rev's website with little fanfare to announce the release. It's listed for eShop release in North American and Europe in "June/July" - so within a few weeks.
Kokuga supports up to four players through local or network multiplayer, but what really makes it special is you get to be a tank. Awesome. It also employs an interesting card system.
