While there has not been any official announcement yet, it seems Konami is not only bringing Gradius back but also its popular Contra franchise. While it is not quite clear whether Contra ReBirth is a new installment or a revamped old title, it does include 2 player co-op. So far only Japan is getting it, next week for 1,000 Wii Points) so we'll have to wait a little longer for more details.
