No, if Mario 3D World won't sell well, I don't think a Galaxy would do better. Especially since 3D World had true local multiplayer and Galaxy is essentially a one player game. That said, I do think they should make a Galaxy game for the next Mario and hope that it does better if they can improve the install base by then, but they should focus on Wii U games we haven't seen before, primarily Metroid and an original Zelda. It would also be nice to see Star Fox, but I won't hold my breath.
