i was thinking that making a new x4 is probably gonna happen and this "that is the last one" thing is just a advertisement thingy anyway knowing what happens in x3 : ( cyclops fate, xavier desintegration and resurrection, etc etc) i came up with an idea that i thing fox will use to bring bacxk people from the death. 1- since they didnt show cykes demise nor they confirm it i would think that cyke is alive but just lost his memory and was wandering around. 2- xavier teleported his mind to the body in muir island and they didnt show the face which i bet was aclone made by xavier and moira which means xavier will comeback to his look alike body in x4 and he will locate scott. 3- the cure to my understanding seems to have a limited time effect, since magneto started regaining his powers at the end of x3 meaning rogue will find out that she is mutant again and she will comeback if not in x4 it will be on x5. What do you guys think? i know its kinda cheap but i feel that this is the option that fox has in order to make an x4. and lets hope cyke will be the leader and will shine in the next movie.
