Looks like I got a couple of my predictions right!

However, some important ones appear (so far) to be wrong....
Based on A15 core architecture - looks like we're still using the same as the original M1:

GPU power:
Recent Geekbench 5 OpenCL puts the 32-core GPU at just over 60,000 - considerably less than the RTX 3060 Laptop GPU equivalent (c. 87,000) I had hoped for (at least in this benchmark - real-world results may be better of course).

Core binning:

14" vs 16" MacBook Pro
This sounds quite plausible to me. It will be interesting to see how good the yields are on the SoC. They might even offer something a bit weird like 14 cores (i.e. twice the 7-core "binned" version of the M1)
