This is a tough question to answer. As much as I love X-men 92, I'm not sure it can thrive long-term with the other X-books. We've seen X-men comics that have been strong at first, but eventually fade. X-men First Class is the last book that did that. But eventually, people just weren't as passionate about it. I think for X-men 92 to succeed, it needs to have a larger vision. It can't just continue to tell the same stories from the TV show.
For me, that means doing things like expanding the cast and establishing new threats that take large arcs to resolve. It's not enough to just continue this series for the sake of sales. Someone has to have a much larger vision. Maybe that vision includes Wolverine meeting up with X-23 and adopting her. Maybe it involves Rogue and Gambit trying to get married, but getting side-tracked along the way. Maybe it involves a new threat like Bastion, John Sublime, Weapon Plus entering the picture. Maybe even Abigail Brand from SWORD can become part of the conflict. The important thing is for X-men 92 to establish a world where there's a certain kind of conflict the X-men need to confront and its a conflict that can't be found in the other X-books.
And if Marvel is going to do something like this, the timing couldn't be better. There's no more alternative to the 616 X-men anymore. After Secret Wars, Ultimate X-men (which hasn't been much of an alternative in over 6 years, mind you) will be gone. So if someone doesn't like the course of X-men in 616, what are they going to do? Marvel wants to keep its customers, doesn't it? X-men 92 could be a way for them to do just that. Take an era of X-men that many remember fondly and isn't quite as bogged down in continuity gaffes like 616. Turn that era into a foundation for a new world where the X-men can function on their own accord without stepping on the toes of the Avengers, Inhumans, etc. I think it could work and if it's successful, it can be expanded. Why not have an X-men 92 alongside an X-Force 92?
It's still not clear whether X-men 92 will have the clout to warrant a new series after Secret Wars. Due to the movie rights, I really doubt Marvel would consider it. And if they did, I doubt they would put their best talent on it like they do with Uncanny and Extraordinary. So it's hard to say what will come of this. But if an idiot like me can create a crappy fanfiction series like X-men Supreme and keep it going for over 5 years and 125 chapters, then I have to believe Marvel has what it takes to make X-men 92 a viable series.
