This is a spin-off to expand the franchise, it wont be another 'X-Men' movie, if that was the case, they wouldnt have announced it with a new tittle, but saying "Josh Boone to direct next X-Men sequel". Not the case here.
Not to mention that back in May with the announcement, one of the sites with sources said that this will be based on the 80s comic and will have a Stephen King/horror vibe (big influence on Josh Boone), so.... its a new roster, not the same X-Men, that wont make any sense, if Fox wants to expand the universe.
The X-Men will be the main franchise, while New mutants will be a second team by their own. The time period more than likely will be different too, taking into account that both Deadpool and Colossus will be appearing on modern day, so Fox might want to crossover those characters with New mutants, same with Cable once he appears on the Deadpool sequel.
