Although I'd like to believe Singer / the writers / TPTB have a master plan for the next movie and beyond, I think it's also very possible they may have adopted the attitude of "let's just do what seems cool now and figure it all out later!" And yes, I agree it seems like a callback to the Kelly eye-flash.

Speaking of missing scenes, where do you think Anna Paquin's missing scene went? I assume it wasn't at the end, given that she had a main credit and was announced for the movie, unlike Grammer/Janssen/Marsden. But if she was in the "future" I don't know where she would've fit in that wasn't as a part of all the X-team. Rogue really should've been depowered in the future too. (Although Charles should've been dead, or able to walk, depending how you look at it.)

Oh, and our Charles/Hank thoughts are echoed by Patrick Stewart. Sort of.
