Latias is probably directly responsible for the Scizor upsurge. I'm surprised that Flygon fell; I predicted a further increase due to Scarf U-turns / Outrages hurting Latias pretty bad. Infernape is standing strong surprisingly.
I can't wait to hear Paltheos' Uber analysis. The statistics are throwing me off.
Many of the just-banned UU pokemon actually FELL in usage.
I believe people dropped their suspects to get a jump on testing suspectless teams. Unlike OU suspects (like Shaymin-S), there was no benefit to abusing UU suspects because ratings were going to reset. As such, practice to get ahead of the game without them.
EDIT: Oh yes, Suspect is super centralized @_@
