I understand that which is why I didn't mention Jean or Hope as their connection to Nathan is obvious. And I wouldn't expect it to feature everybody that's ever been in contact with Cable, but my comment was simply the implication that Rogue, Rachel, Colossus, Rictor, Deadpool or any of his ex-X-Force teammates would have made more sense in relation to Cable than Storm, Iceman, Beast and Nightcrawler, who haven't had significant panel time with him AFAIK. Now, this might have been the writers choice, or the cover might not be a true indication of who's in the story or their role, but I was just making an observation, and I think you've taken it in the wrong way.
Anyway, I get that X-Force is dealing with the issue on their own terms, but my perception was that this issue deals with Cable's death right after Extermination, and we'll probably see a funeral and such, so it would make sense for the X-Force to be present BEFORE they seek out vengeance.
