Why would you expect the base M2 to be faster than the M1 Max unless you originally picked the wrong processor for your workload? You've got twice the performance cores, 2-3x the GPU cores, a second media engine etc. so the sort of generation-on-generation 10-30% improvement in single CPU/GPU core performance isn't going to beat out the extra cores on multithreaded/GPU-heavy/codec-heavy jobs. Plus you've got the extra RAM, I/O and display support to factor in.
The only people who might be affected are people are considering buying the M1 Pro, especially the cheaper 'binned' version. Even so, the M2 probably won't do better than give the M1 Pro a run for its money - and the Pro still has better I/O and display support - so it's not going to be worth considering as an upgrade.
If/when a M2 Max comes out - with the extra cores and I/O - you'll have a comparison to make. Even then... these days I wouldn't be looking for a must-have upgrade on a "pro" computer until it was at least 3 years old. If the M3 Pro/Max comes out in 2024 and offers seriously better performance because 3nm then that's about right.
