I certainly hope I won't have to buy a PS3 in the next few years. Good to know most of the good recent shmups of the last 1.5 decades have already made it through on the x360 (best Cave, Seibu, and Treasure at least). >_>
[EDIT]
Ah, so Chiyomaru is going for multiplatform, not PS3 exclusive, that's a good move indeed. Hope it'll turn out alright for 5pb, we need more active shmup developers nowadays to keep the genre as alive and fresh as reasonably possible.
