I’m still trying to decide if I should wait for next iPad Pro 12.9” or just get the current one. It’s reasonable to expect some sort of CPU bump (‘M1X’ or ‘M2’) but it might just be a higher clock rate. (I found this amusing Apple M series table:
https://cpu-benchmark.org/apple-cpus/apple-m-series/).
And it seems no OLED is rumored until next year…and I don’t want to wait that long. Of course if I do buy now, they are sure to come out with M2+OLED edition 3 months hence.
