According to one interview with Chris Claremont, GeNext is supposed to take place 10 years after the events of X-Men: The End, although as the series progresses, several characters who have died in X-Men: The End are revealed to still be alive, such as Cyclops and Gambit. GeNext was planned as a five-issue miniseries, with a sequel mini-series published in 2009.
The story line was originally conceived with the idea of the X-Men aging in real-time. In an early 2006 interview with IGN, Chris Claremont summarized the concept as followed:
The series takes place in 2006 and follows continuity up through X-Men Vol. 2 #3. While the public believes Magneto is dead, he decided, in actuality, to disappear from the public eye in order to live in peace. "The '90s never happened," Claremont said, referring to the continuity break and perhaps the dark period full of bad X-Men stories.Some 1990s characters appeared, such as Stryfe and Cecilia Reyes, both of whom appeared in X-Men: The End. In the February 2006 IGN interview, Claremont also mentioned that Xavier and Magneto were both alive, contrary to the X-Men: The End storyline, though he stated in a May 2008 Newsarama interview that "Charlie has moved on and so has Magneto. They’ve died over the last twenty years."
Cyclops and Gambit, who both died at the end of the X-Men: The End storyline, are shown to be alive in this future, with Cyclops still running the school with Emma Frost, though both fell out of touch with the X-Men after Rogue's death, as Gambit barely speaks to his son Olivier, doing so only through Olivier's sister.
