I know that everyone and their mother is jonesing for Apple Silicon replacements to the MacBook Pro (16-inch, 2019) and MacBook Pro (13-inch, 2020, Four Thunderbolt 3 Ports) and particularly because it will bring a new redesign, but I must offer a few words of caution for those who would be early adopters:
There have been four body styles of MacBook Pro to date. The first one or two releases of those body styles (four in the case of the original and three in the case of the unibody) had serious issues that affected reliability and/or functionality and/or usability in at least one size of MacBook Pro. In some cases, quality repair extension programs were issued, but in all cases, there wasn't much of a fix because the issues were inherent to the design and/or parts used. With the exception of the first design generation of MacBook Pro, usually the most reliable release of MacBook Pros from within a given generation are the last one or more, rather than the first one or two. The original design generation (that largely continued the design of the aluminum 15" and 17" PowerBook G4s) is a notable exception (in which pretty much all of those sucked), but this has otherwise largely been true of all of the design generations of MacBook Pro, especially for the Retina and Touch Bar iterations.
All that to say that if you're determined to be an early adopter on this new generation, consider that the odds of you having issues with what you buy will be greatly increased over waiting a refresh or two.
