Looks like we can certainly expect a lot more revivals from WayForward on the Wii. LIT has been released on the Wii's WiiWare service already.
This positive reception inspired the creative team of Shantae and Contra 4 to now look more to revival games like Metroid, Rygar, Ghosts and Goblins, Dig Dugg and more. They also clarified that LIT is already in development for Europe right now, and will in fact be available this summer for European gamers.
We'll be looking forward to all those cool retro games as well.
