Like many others around here, I'm really loving Wolverine and the X-men and Uncanny X-Force and hope they remain untouched. Having said that, I just don't see how Bendis would be able to come in and "relaunch/revamp/reboot" the X-books without using their biggest star. I would personally love it if he did, though, and just stuck to the Blue side books like Uncanny X-men and X-men and the characters on Utopia right now. Throw in Cable as the ex-military, grizzled old badass / loose cannon of that group (i.e., their Wolverine) and put some superstar artists on those titles and it could be like Bendis' early New Avengers run where it was selling through the roof. I think having Steve McNiven, for example, doing Uncanny X-men (rotating with Pacheco) with Brian writing and them handling the X-Tinction team (minus Danger and plus Cable) could be great. Have the Blue team branded as outlaws in the aftermath of AvX whereas team Gold gets a pardon due to Wolverine's status as an Avenger or something (plus he'll probably end up on the Avengers' side by the end anyway). The X-men team would continue to act as the Blue side's security/recon team with Cable also on it plus Storm, Warpath, Psylocke, Jubilee and Domino. And I say put Coipel on that rotating with this Mollina guy who did the most recent issue. I'd enjoy both of those.
But I guess that's not much of a relaunch. More like just bringing Bendis on as writer and adding a couple of superstar artists and pretty much keeping the teams intact (but adding Cable).
No, something tells me that if Bendis comes over to the X-books the changes will be more substantial than that and a lot of the current "Regenesis" structure will get completely torn down, as he will want to play with all of the toys and not just those on the Blue side of the fence. Which is a shame IMO, as I'm finding the Gold side books (and particularly WatXM and UXF) to be the most interesting X-titles since Grant Morrison's New X-men run. If there was a way to leave them alone and just have Bendis revamp the Blue side titles I would love it. IMO there are enough interesting characters on that side or not on either side (e.g., Cable) to make for some compelling team books.
