“Basically, if John Byrne didn’t come up with it, we’re throwing it out,” said Van Lente who noted that through no intentional malice, the team had been subjected to a lot of bad continuity over the years. “I wouldn’t say we’re ignoring everything that came later, but we’re not going to be referring to an individual character’s multiple resurrections over the years…this is one of those stories that wants to start with a clean slate,” Pak added.
As for which characters will or won’t be appearing and how, the team heavily hinted that Puck will appear in the series, and asked whether Northstar would continue his role in the X-Men line, they said that elements from those stories will make it in – including Kyle, Northstar’s boyfriend from “Nation X” – but overall he will become a full-time Canadian again.
Well, I'm sold.
