No one should want an intel 16" macbook this year. While it's possible that Apple will do it to buy some time:
(a) Intel doesn't have Tiger Lake available yet in 45w (35w now), so it would just be another disappointing 10th gen release if they did it this fall. Additionally, Intel doesn't even have a hard date yet for that Tiger Lake chip, just estimates, which is terrifying. The only major upside I see for Tiger Lake is the built-in hardware AV1 decoding which Apple seems unlikely to support in this new Apple silicon, given that the new iPhones don't support it.
(b) Given that Apple is going to phase out intel over the next couple years, it probably limits the lifespan of a $2500+ 16" intel macbook to maybe... 5 years until the OS is so out of date that you can't really use it anymore?
For comparison, the 2011 macbook pro with the sandy bridge chip got it's last operating system with High Sierra, 6 years after release.
