Don't Wait if you Can't Wait Several Months
Can you wait until at least March for the 2020 MacBook Pro release date? If you can't wait that long, or longer, then you shouldn't be waiting for the new MacBook Pro at all.
Apple typically announces a new MacBook Pro in May or June, but in 2019 they split it up into May, July, and November.
If Apple updates the 13-inch MacBook Pro separately in 2020, we could see a new model in March. The recent filing with the ECC points to a potential Spring release, so that gives some hope -- but March is still months away.
This isn't guaranteed, and in all likelihood, you will need to wait until the middle of the year for a 2020 MacBook Pro release date.
