The only thing that needs redesigning is an ability to connect at least two external monitors to an Apple Silicon laptop. It's not a Pro laptop if it can't drive two external monitors, as a lot of professionals (in different occupations) need a multi-monitor setup (at least two external monitors). I had to resort to a DisplayLink dock to drive a second external monitor. I was fortunate to find a great DisplayLink dock, but the research and trial-and-error process took a long time. Still, DisplayLink is a bandage on a very serious shortcoming of the M1 graphics capabilities (or lack thereof). I'm still hoping that Apple can enable a two-external-monitor support on M1 laptops with a software update.
Other than that, the M1 laptops are much superior to the Intel laptops in the same category. The M1 MacBook Air blows out of the water anything Intel based I've used by Apple. It's just an absolutely mind-blowing performance with no spinning fans. So, there may not be a pressing reason for Apple to release updated MacBook Pros this year, especially because Apple execs don't seem to think that external monitors are important - otherwise they wouldn't have discontinued their own affordable external monitor. They may be focusing on a 27" or 30" iMac with the M1 architecture.
