Do you think they will ever feature in the X-Men films then? Both Fox and Marvel share the rights, so it's possible.
Its too complicated so unfortunately they'd probably will never see the light of day. If you can't utilize their full characterization then don't use them at all. In respect to the integrity of the characters I think that was the best move.
