Based on this cover art, it looks like the new comic will feature Psylocke, Storm, Rogue, Rachel Grey, Kitty Pryde, and Jubilee.
According to Marvel’s press release:
An old enemy shows up at the X-Men’s door, seeking asylum from an ancient evil come back to Earth. Meanwhile, Jubilee has come home, and she’s brought with her an orphaned baby who might hold the key to the Earth’s survival…or its destruction! With an imminent alien invasion and an eons-spanning war between brother and sister around the corner, Storm steps up and puts together a team to protect the child and stop a new threat that could destroy all life in the Marvel Universe!
However, the art will be colored by Laura Martin so Escher Girl poses should be kept to a minimum.
