Oh yes! I'm sorry--I misread something you wrote.
I thought you asked what talk was regarding X-Men 3, and I just realized you asked if there was talk about making an X-Men 3. My mistake.

Yes, X-Men has been meant as a trilogy from the beginning. I do know that much--that when the original X-Men was made, just like with Spider-Man, they intended it to be a three-movie deal. So, yes, there is definitely supposed to be a third film!
