So long as they keep a good creative team on board, I would prefer the X-Men not go over to Marvel Studios. If that were to happen, they'll be lucky to get a single movie every 4 years or so, and some cameos in the big crossover films. Wolvie would probably get his own series again, but. . .still. X-Men deserve more than that. They shouldn't be hamstrung by thinking about crossover movies 5-7 years down the road, where this or that plot element has to be integrated. And more is better, so in my mind, the current strategy of adding more spinoffs is a very good thing in theory (even though Channing Gambit sounds like a baaaad idea on its surface). But if we ever get to the point where we consistently see mundane, forgettable movies on the order of X3 or Origins, then I would rather just see good X-movies done less often, where the team plays second fiddle to the Avengers and Spidey over at Marvel Studios.
