See, I thought that originally too - but then, that arm is literally all that remained of Wolverine after Ultimatum. And even then, everything living had been boiled away. I think Ultimate Cable, as with the March On Ultimatum FF/X-Men characters, are all by now basically just alternate universe characters - not from further in the timeline in the current universe. I mean, pretty much no-one in the March On Ultimatum story is in any position to adopt the roles they're meant to take on in the Ultimate universe's future after Ultimatum. In fact, the entire thing makes absolutely no sense since Cyclops and Wolverine both get whacked as part of the same storyline anyway.
Exactly. They were all stuff that COULD have happened. I'm glad they didn't happen though.
