Haven't heard anything about Wii or PS3 getting anything, but Treasure has announced that they're making a new vert shooter for the 360. There was an interview with 1Up or something like that... There's a thread on it around here somewhere, hunt it down for links and discussion and whatnot. ^_^
milestone has announced a shooter for the wii. it will proabably be karous / crows that will heads the way to the wii as it's also making it's way to the dc. there is a thread on it around here too.
That actually had me a bit confused too, but I didn't mention it. Anybody who frequents this board could answer the question, since this board is a very reliable source of shmup news. People are very good about posting stuff they find out here ^_^
