U forget about Rebecca Romijn in FC! Yeah but I hope it's not dream sequence, IMO a post credit scene will be awesome. Whether she warns Logan about the impending doom or just a badass scene with the Phoenix bringing Jean back to life. Something like this from X-Men: Pheonix - EndSong
Obviously they can't recreate that word for word or even panel for panel, but I sincerely hope they try do something as spectacular as that. I think that would be thee most awesome post credit scene ever, and a sure way to get fans ecstatic for DOFP.
