It could be quite possible, around the time MM3D was announced, a February release date accidentally appeared in a site(Nintendo's UK one, I think) so a February release date for that seems accurate, and if the game is having small features exclusive to the New 3DS, then it will either release a bit after the New 3DS or launch alongside it, which seems to be the case.
So it does seem quite possible, and a February or March release for the New 3DS is pretty much confirmed, since it would be the only thing that could make Nintendo reach the 3DS family FY14 goal, plus it seems there are already European New 3DS being produced, unless that Ambassador program sells Japanese New 3DS.
