A nice bump in specs, but nothing groundbreaking like the initial ship. Somewhat disappointed that AV1 isn't supported in hardware, and Apple's continued push with HEVC gives me doubts they'll support the codec in the future.
Given that the M2 is based on the A15, which doesn't have AV1, this was kind of expected. I'd imagine that, due to their general cycle, AV1 would come to iPhones first if/when it arrives.
Anyway it seems likely the engineering tradeoffs made in the overall M* architecture will be with us for several years to come at least, and the first few generations will be incremental improvements.
no need to be disappointed, you can just look to the iphone for the next macbook.
