And I also want the OT'ers to have a turn in Apocalypse. Imagine something really sweeping, that doesn't involve time travel. We see the 80's X-Men facing Apocalypse, while at the same time exploring his origins (via flashback/telepathy) in ancient Egypt. They win a battle against him (or so they think) and he mysteriously disappears, only to re-emerge to finish his plan against the OT X-Men. I'd love something like that.
Thats why I said before Titansupes! Hopefully it works out that way!
