Warren was part of the mass resurrection that happened in the recent minis by Gillen. I doubt if there were will ever be any sort of fallout from Dark X-Men to talk about, seeing as Warren ends up coming back with no problem.
Thanks. I thought that X-Corp comic dealt with internet stuff, but I thought that I might have forgotten something from an earlier X-Corp appearance, or even something from one of the PoX or HoX comics.
