Natsumeís Omega Five, an XBLA shmup coming to Nintendo 3DS next spring in Japan, according to Famitsu.

I donít remember this co-op title from when it came out for XBLA in January 2008, but it seems to have received generally positive reviews ó 1UP, however, called it ďtoo hardcore for its own good ďand [not] anything specialĒ. I hear the music, composed by Hiroyuki Iwatsuki (Pocky & Rocky, Gundam Wing: Endless Duel), is great at least.

This would be great as a 3DSWare release, though I have a feeling itíll come out as a retail cart, three or four times more expensive than its $10 XBLA edition. I hope that doesnít become a trend with XBLA/PSN-to-3DS ports. Itís bad enough already that $0.99 iPhone games are releasing on Nintendoís download platform for $5-$8.
