I desperately hope you are correct, but my guess is if it were at a point where it was possible to define a release window then there would have been one in the teaser. To be clear, I'm not saying I think it is a ways off. If my assumption that a release window cannot be defined at this point is true then the only reasonable conclusion, in my opinion, is that any given date is equally likely. So it could be Valentines Day, or it could be Christmas.
