IF they decide to implement USB PD which is not a necessity. some of the rumors this week suggested MagSafe only. For the expected 12+ hrs of battery life, I'm not sure of the benefit of faster charging, but I'm sure some will find it useful, I don't as it negatively impacts battery longevityOfc you will still be able to charge over usbC, but with magsafe you can charge faster and keep 1 usbC free by doing that
Yes m2 I expect will be in the 16” with bigger unifed in SoC gpu
