Third parties should announce their own stuff. Nintendo is a developer also and they shouldn't have to shill other people's work constantly
Yeah, though it's a bit early for a main series game without it risking damaging BW's sales like FRLG dented RS's.
That said, I believe that any main series games this coming year will be DS games with MAJOR 3DS enhancements.
My bizarro theory is; Third gen remakes. Two games, counterparts of eachother. One is a remake of Emerald and has you go through Hoenn first, then end up going to Kanto afterwards while the other game is a remake of FRLG and has you go through Kanto and Hoenn afterwards, with the second regions being set later than it being in the other game, but the wild Pokémon in the games being the counterparts from the originals.
Or they'll just be RS remakes :P or the third game
