She's going to sing Dark Side. It makes no sense to sing Stronger unless the BMA's requested for her to sing it since it was so massive but I doubt it. It's not the Grammy's.
Given that the music video was only a one day shoot there can't be much editing needed so they're probably planning to release the video right around the BMA's since people will be wanting to search the song after she performs it. Then radio will hop on board, the premiere of Duets.. she's going to be all over the place. It's really smart (and lucky) timing that Stronger did so well for so long so she can have all of this happen at once.
As long as radio supports the song (which they most likely will given the success of Stronger) then she has everything she needs for the song to be at least as big as MKIA but I think it will be bigger. MKIA didn't do badly at all but how rare is it to have the lead single be the worst performing single on an album?
