I'm just flipping thrilled KT is handling it. She's the best X-writer I've read in a while. She's also very aware of fans' concerns, so I think she's going to try her best to be fair to fans of each character.
I guess the reaction to R+G (letters sent, hype, etc.) must have been huge beyond sales alone. I hope they continue to have more team-up titles with other characters, even if they're minis. It's the best way to get more character development. I'm tired of buying team books for one or two Gambit scenes, you know? So yeah, this is such great news.
