If you can wait, why not wait.
Intel MBPs are going away soon with a 2 year max timeline. Apple says by the end of the year they are bringing out Apple Silicon based systems. If you can wait until the end of the year or even better this time next year the MacBook landscape will have change quite a bit. Also, anything you buy now is going to take a hit in depreciation.
A couple things.
You will still get support for at least 4 years on a mbp you buy this year.
You may want to avoid 1st rev hardware and software compatibility.
So I think the sweet spot for transitioning to the established version of the new platform is mid-2022, although it could be sooner.
Windows is still supporting Intel CPUs, and it runs on the Macbook Pro.
Worst case scenario, instead of recouping at least 50% of the value in a resale in 2-3 years,
you recoup 20 - 30% of the value, the buyers market being people that want to run Windows on solid hardware.
And that lost value is perhaps gained time on not being a beta tester, working on a solid hardware platform with software support already.
