I think 4 games for the 3DS is good and 2 games for Wii U would be okay if the VC on Wii didn't exist
I hope those being Ambassador games is a sign that they're running out of stuff to release. Fingers crossed for GBA.
As noted by a thread I made earlier, they're not too far from running out of stuff to release in Japan too. So I'm betting on SNES (maybe GBA?) games being announced soon.
