Alright, so this is a thing that's been bugging me again lately, and I'm just gonna throw it out there.
I notice that a lot of people, in forums, reviews, solicits, and what have you, keep referring to the "O5" from All-new X-men as though they are seeing their future. But here's the thing, the "O5" in All-new X-men aren't the 616 versions of those characters. By definition, they can't be. They didn't start out in the 616 universe to begin with.
This is where we first meet the All-new X-men:
Basically, it's the same point in their history as the events that took place in our (the 616) X-men's reality in The X-Men #8from 1963. Except that it's not. This is how that event went down in the 616 version:
See the difference? The dialogue has been changed. It's not a big difference, and if it's the only thing that distinguishes that version of history from the original, it would mean that these should be basically the same kids. But keep in mind, the scene from All-new X-men #1 takes place before the future/present/616 Beast has any interaction with these kids at all, so there's no explanation for why the discussion they were having would be effected by that; the only explanation that makes sense in the context of the story is that this isn't in the 616 X-men's past at all, even if it is virtually the same.
I'm just pointing out that that it's different at all means that, by definition, these characters are from an alternate version of the X-men's history, ie: an alternate or parallel universe.
One could point out that if all of the characters in the story believe that they are seeing the actual past/future versions of themselves, including the 616 Beast, then of course they would respond accordingly. Thus, the point I'm making needn't really have any impact on how this story goes down, I'm just pointing out that, as readers of the story, it should be recognized that they are obviously not the 616 versions of the characters.
I don't know if this is a thing Bendis intended or not by changing the dialogue. Part of me thinks that he could have done so to leave himself a back door to do whatever he wanted with the characters, without having to worry about it effecting (the established 616 version of) history. This way, readers can see stories with the X-men when they were young, in the present, without writers having to later explain why that experience didn't effect history.
It also gives Bendis an explanation for why this All-new O5 might behave in ways that seem out of character based on Stan Lee's versions of the characters, without having to do any disservice to Lee's canonical version. If it is intentional, it's actually pretty clever.
