Hmm... I was thinking about this in the Cable Appreciation thread, and lamenting the fact that unfortunately it doesn't sound like anyone has plans for Cable in the upcoming Fall of X story. At least not yet. I suppose it's possible he shows up in Duggan's X-men, as part of the roster shakeup there. Would love to see him back in Duggan's hands, as he wrote an awesome adult Cable in his Uncanny Avengers run.
But then it dawned on me... could be he in this new Alpha Flight? I mean, the last version of Alpha Flight was a space-based response unit, and Nathan is currently an Agent of S.W.O.R.D. So I suppose that's a possibility. If so, it would make sense for Monica Rambeau to be there too with him. If that's the concept, consider me onboard!
