The thing is that it is really hard to have jean back in x-men because she can now destroy an enemy in an instant. Imagine Onslaught or Apocalypse being part of the X-Men? So in anyway possible Marvel will be powering down our dear Jeannie, but if Jean becomes a part of avengers... well that's a diff story... they can even battle to other unviverses
