I'm predicting Rogue's rampage gets the Avengers attention and they go to take her down or she just encounters Cap and he slips one of those inhibitor collars on her. Either way, Rogue's goin' down and the X-Men see this on the news and go to Genosha to free her. Combined with what happened in episode 5 and this, "Earth's Mightiests" picked the wrong time to take on the mutants. Before the X-Men can get to Rogue tho, they have to go through an army of Sentinels still hovering around Genosha. I'm thinking this is where Storm come back with a big re-introduction. How does Cable and Bishop figure into all this(since I assume they'll be back this episode too)... who knows?
Of course I could be wrong about all this
