Yes and regarding the Sentinels, I think that now Transformers will make a standard for giant robots on film. Fox will become more open to that idea. We will have Sentinels in the next film. Not mentioning that it is the only plausible and logical path the story may take. The newly formed team is perfect for battling the Sentinels. The Last Stand didn't put an end to the story. Let's have one more film with Magneto and let's put an end to that story.
X-Men: Zero Tolerance
The Government in fear of the mutants, after Magneto's first open attack on humanity and Phoenix's capabilities of mutant power, decides to put an end to the mutant threat. Knowing that the cure was not permanent and that the cured mutants will develop their gifts in time, it decides to make a peaceful proposition. Magneto is given a land to rule his kind. As mutants from all over the world migrate to Genosha, the X-Men are faced with unrest by this fact and without the guidance of Charles Xavier begin to disband. In the end a darker scheme is revealed as Magneto's darkest fear realizes, the Genocide. An army of giant robots, created for sole purpose to destroy mutants, attack Genosha. When all hope seems to be lost the sudden appearance of Charles Xavier reunites the X-Men for a final encounter with Magneto.
Now I know that this doesn't belong here, in this thread, but Apocalypse will simply not fit in the next film. Apocalypse is my favorite character from the Marvel Universe, maybe the most complex one. I would like for them to really put an end with the fourth film. And then if the film does great, for them to make two more. The fourth to deal with the Hellfire Club and Sinister and the return of Cyclops and the resurrection of Jean. And finally the sixth with Apocalypse. I would like to see Apocalypse as he is, "the first one". Though I would not appreciate him being with cyber technology. The most perfect Apocalypse, that will fit in the film, is Xerxes from 300. Whenever I watched the film I saw him as Apocalypse. I cannot see the character to work otherwise with the well established mood and credibility of the previous films.
