Well, we know it's not a reboot. A partial one, I would say. It rewrote what it wanted to, but it's got unmistakeable cues to the original trilogy. Going on, creating a sequel that ignores the first trilogy (or at least the first two movies

) would make for a lot of wasted effort on behalf of those who worked to make
First Class part of Singer's world; the Magneto origin scene, Raven's blue form (and being naked,) Jackman's Wolverine, Cerebro sequence, the X-Jet, etc... It just didn't feel like a reboot, it felt like Singer's X-Films, save for the sharper pacing. If they wanted to reboot it, they should have gone guns blazing like Spidey's new flick. But they knew how good Singer's films were. I mean, they created the formula for the modern superhero movie. They should just build upon their loose (aka "ignoring
The Last Stand and
Wolverine") prequels. So, no, no Iceman. Jean and Cyclops at some point. Angel's a very big maybe for me. Only because his ability and his character are not nearly as interesting as others. If they wanted to, they could use him, though. I don't think any more contradictions to X3 will hurt the continuity more than
First Class's have. I mean, I'd love to see a rebooted Blob in the Brotherhood since Magneto doesn't currently have any muscle. I guess my point is, a full-on reboot would bother me because I still enjoy the first two films so much, and
First Class fits pretty well into their continuity. I want a sequel that will too. And as long as they don't use characters like Rogue, Iceman, Pyro, etc.., they should be fine.
