Last rumors say Marvel Studios will go for a complete reboot of X-Men, because the price of the contracts of some actors (especially Michael Fassbender and Jennifer Lawrence; also, Jackman is unlikely to come back) is going too high.
So, no Secret Wars for now.
Also, it's been reported the supervision of the development X-Men films is already under Feige's control. He will decide which films to greenlight and which ones to kill. First thing he's done, it seems, is killing the X-23 movie. I guess because it'd be part of the old continuity.
