So, as most of you know, Gamefreak has not revealed a new main series Pokemon game. Which is kind of odd since they normally release annually. The stuff they have announced aren't really big projects and they are basically all done. So, what are they doing? Are they just deciding not to release a main game this year? Are they making something bigger? New IP? Wii U Pokemon game? 

This is all speculation as we really do not know what they are doing. All options are realistic. Keep it civil guys.

Tembo the Badass Elephant 2

Pokemon of course.

Maybe a Stadium type game for Wii U or 7th gen Pokemon, I think their 20 anniversary is next year so either one for the celebration.

They just released a new IP, lol.

I've said this numerous times, but, next year marks Pokemon's 20th anniversary they're doing something for that.

They're working on next year's Pokemon game for the 3DS. Likely X2/Y2, Z or a new gen.

Or some spinoff for the Wii U, but I kind of doubt that at this point.

I would like a new Pokemon like GC's Colosseums for WiiU.

There's the problem. They don't release annually. Between HG/SS and ORAS, they did... But before that, Pokemon wasn't a yearly release. They should be working on Pokemon Z, and keeping contact with Nintendo for the next handheld for Gen VII.

They were working on Tembo after ORAS probably... Was it the same Pokemon team? Doubt it, but I don't know.

I think maybe they're either skipping a year for Pokemon or maybe even making a game for whatever the NX ends up being.

Even if a Pokemon game were to be released on WiiU, it wouldn't be done by Gamefreak.

But isn't the 3DS technically Nintendo's 8th gen handheld?
