I'm pretty sure they're going to throw a curveball. Even Nintendo can't be oblivious to the death chant being taken up around them.
Now, that curveball might be completely ineffective: Surprise SNES Remix, F2P NFC game launching imminently, Pushmo Deluxe for WiiU, WiiU ports of Kid Icarus: Uprising and Luigi's Mansion 2, HD remasters of N64 classics, etc.
I'm keeping expectations low, but I would definitely be interested in meaty DLC for Super Mario 3D World.
