Twentieth Century Fox is not about to allow its X-Men license revert to Marvel for any lack of activity.  A sequel to Wolverine starts production in August, followed by a second X-Men: First Class film, which should starting shooting in January of 2013.  But Fox President Tom Rothman hinted very strongly to a correspondent from Collider that a New Mutants movie was in development and would like be announced at Comic-Con.
 
Created by Chris Claremont in 1982 for Marvel Graphic Novel #4, the New Mutants were a group of teenage mutants in training, who received their own comic book series that ran from 1983-1991, followed by a second series from 2003 to 2005, while a third series, which reunited most of the original team was launched in 2009.  Given their youth, and ethnic diversity (the original team included a Vietnamese girl, a Scotsman, a Brazilian, a Native American, and a Kentuckian), the New Mutants would appear to be perfectly constituted to appeal to the increasingly important overseas audiences.
 
As for projects that are definitely on the schedule, Rothman also revealed that the location shooting for the Wolverine sequel will be done in Japan, with studio scenes shot in Australia, and that Matthew Vaughan, Jane Goldman, and Simon Kinberg were all working on the screenplay for X-Men: First Class 2.
