This was actually something GAF's very own Busty was talking about a few weeks ago, but looks like it's picking up steam a bit with other outlets now:

And both Patrick Stewart and James McAvoy met with Kinberg recently, with McAvoy hinting at shooting this summer.

So looks like that "X-Men: Supernova" rumor may end up being true after all.
After talking to multiple sources, I can report that writer/producer Simon Kinberg is looking to make his directorial debut with the next X-Men movie and hes already written the screenplay. From what I hear, it does focus on the Dark Phoenix storyline and its now up to the studio if theyll use his script and if hell get to direct it. At this point, I dont have any information about casting beyond Sophie Turner.
