Yeah, I get that, and at the end of UXFOR2 Psylocke says that she is not returning to the school meaning that she is meant to go from UXFOR2 to XFOR4.
A few more considerations:
- in ASTONX3 62, which happens 1 month after the X-Termination crossover, Jubilee is in a phone call with Gambit and she hints that she is considering returning to...(implied to be the school). Well, it could be assumed that she was at the school for X4 1-3, then left again, because in X4 4 she goes with Wolverine back to LA, so she could've just stayed there.
- in ASTONX3 64, Wolverine & Gambit visit Dark Beast in jail, where he was put after his actions in the X-Termination crossover. Dark Beast appears as a masked unidentifiable villain, at the end of UX3 11. So he couldn't be in jail at that point. And imo, this is the biggest evidence that ASTONX3 62-65 should be placed earlier in the chronology.
- in ASTONX3 66, Jubilee already appears with the rest of the team (could just be visiting, and not be part of any field team), but NYC is still recovering from the iceman's ice storm, so I don't know how X4 1-3 could fit between ASTONX3 65 & 66...
- Oh and Mystique is involved in the ASTONX3 62-65 plot as well, so yeah, she definitely multitasks
Still, I think that with current placement of things in this era, X4 1-3 should be moved forward. Unless there's a reference somewhere else that I'm overlooking.
Anyway, here is my shuffling suggestions (X-Men books only), not only to deal with this matter, but with some of the issues I brought up earlier:
