I think you are slightly overestimating the sales of Pokémon OR/AS. Remakes usualy don't sell as much as a new gen. X/Y did incredibly well partly because of the new 3d graphics (and obviously it's pokémon). It sold 11mil atm. OR/AS will clearly sell less than that. The thing is that they will only have 2months (november/december) to sell units for the year. It will sell around 5mil at most. (I know I'll be picking up a copy :D)
Back on topic, I think MK8 will win. It's already standing at 2mil, the best selling exclusive of the year atm. The thing with MK8 is that it will keep selling healthy amount of units all year. It will have a big boost on the holidays, I even expect it to go back in the top 10 despite the game being half a year old. If it's bundled it will be a given.
Halo has a shot. But I don't think smash does. Smash on 3DS will sell really well but less than the WiiU version. And the launch of WiiU's smash will bring a boost of WiiU hardware bringing a boost in MK8 units (even more if it's bundled). So despite Smash doing really well, it will only help MK8 solidify it's head start over all other games.
