I wouldn't go just by the rumored specs. Apple still manages to surprise me pretty often with some of their releases. For example, while we do now have iPads with M chips in them, the star of the show for those chips has largely been the Mac. I could see Apple doing something like pumping new life into iPad sales by introducing an all new Pro lineup with M3 or something crazy like that. I'm not saying they're doing that this year, they most certainly aren't. I'm just saying they are known to do things like that from time to time with all their device categories and it tends to throw people for a loop.
EDIT: My point is, I never say "I'm not upgrading this year" anymore until I see what my options are.
