I'd like to see that storyline. For a while it looked like Genosha was going to get rebuilt, but then Decimation, and then The Collective, and then kind of nothing. It sort of seemed like there was a hands-off policy regarding Genosha. It got mentioned a few times in X-men storylines (mostly by Emma Frost), but no detail, no idea if people still lived there after The Collective thing with Xorneto.

The Necrosha storyline supposedly includes a bunch of Genoshans getting resurrected, but I haven't read it yet, as I trade-wait. I'd guess they re-die, leaving individuals important to us around.
