Not really sure if this is a good idea for a game... but I always enjoy guessing release dates etc, and I think I'm better at it than analysts. The idea is you just make vague predictions here, like "Zelda U will be released in 2015", and then you get to brag about it if you're right.
You can also make other predictions ("Retro's new project is Metroid Prime 4" / "Pikmin 3 will be delayed until 2014"). We could work with points if anyone wants, or even betting ("your prediction is so unlikely, I'm willing to put 10 of my points on the line").
Retro's new project
Zelda 3DS (either Majora's Mask or a new one)
Mario & Luigi 3DS
Good-Feel (Shake It/Epic Yarn developers) new project Wii U
No More Heroes 3
Super Mario Universe (new mainline 3D Mario)
Zelda U (new mainline 3D Zelda)
