Extermination leak - this event is supposed to be a hard reset for the X-men timeline, meaning that not only that 05 will be sent back, but also that any time-displaced mutant will GTFO as well. In other words, bye bye Bishop and Rachel Grey. Also, Cable will get an ongoing that will deal with the new status quo and repercussions from that event in January 2019. Apparently, the new Cable will be more like Nate Grey (X-Man) in terms of look and history.

The only source is sadly my ass for now, but few months from now you will say "wow, that anon was probably some insider"
