Nothing concrete. However, I've posted before that I think the only reason mu-12 is being included now is because the arcade release was cracked, and her inclusion as a console-only character is supposed to encourage us to buy the game.
So with that in mind, it wouldn't surprise me at all if they just slapped together a moveset without actually balancing her.
EDIT- Found an article that discusses this stuff (not necessarily whether she'll be balanced or not though)
