At any rate, even if it doesn't quite happen now, I would like to see other Pokemon games get the BW2 treatment, I think there's a lot of potential in something like that.
2014- off year that releases some 6th gen spinoffs (probably 6th gen Mystery Dungeon and Ranger), maybe even XY DLC
2015- some sort of RS related game
2016- another off year, more spinoffs
2018- another off year, even more spinoffs
2019/2020- 7th gen (the 3DS' successor will likely be out around then anyway)
