Whilst responding to fan questions in his "Cordially Chris" forum on the X-Fan Message Board, X-Treme X-Men writer Chris Claremont has revealed that he will be introducing some new regular cast members some time between issues #10 and #14.
During that period, Claremont said fans can expect to see Moonstar, Forge, a still-depowered Wolfsbane, Shadowcat, possibly Rachel Summers, and a new human character - who will fill a role similar to the one Madelyne Pryor played during Uncanny X-Men's Australian era - joining the cast.
Claremont also hinted at something involving Jean Grey in the pages of X-Treme. "We may have a surprise or two in store in that regard," he posted.
Claremont then addressed a follow-up question regarding the number of members on the team, saying, "There won't be 10 members in this title. The core team will remain at 5 for the foreseeable future, with add-ons depending on the demands of the various stories. At this point, I have no thoughts of culling the team further, but who knows? I may get a better idea. Also, membership depends on reader reaction to some of the new characters we'll be introducing during the 'Oz' arc. If they catch on, again who knows?"
Like I said, Wooooo!! Rachel, Jean, Kitty, others... ;)
