May be sparrow did not see the movie as the ending was obvious !!! once he kills the omega, his eyes lits up and he awakens in his helicopter(earlier than previous repeats).

On logan/prof X, Fox could reboot it again. I hope he meant that.

I don't remember the movie as well as I thought but yeah that was my understanding that Blunt dies in the end. Nevermind then, my question still stays are both the leads confirmed to return?

Logan/Prof X was not me, it was zwackerm and you should really read his review about Logan to understand this and that are not same.
