As other's have said, I would wait at least a month if you can. The iPad Pro refresh seems to alternate between March and October on an 18 month cycle. While this March is only 12 months, I don't really count the 2020 iPad Pro. It was quite literally LiDAR, 2GB of RAM, and one additional GPU core. The fact that the Magic Keyboard worked with the 2018 model was another tell the this was mostly a spect bump to avoid the narrative of "two full years" and to start pushing LiDAR.
I am also tired of waiting, but will continue to do so. I had the money ready to go in March 2020, but couldn't bring myself to pay top tier prices for essentially the (admittedly good) 2018 model redux. My 10.5" iPad Pro isn't doing great, it has developed severe "white spot" toward the bottom and the battery is only useful for a few hours, but it's out of warranty. If the iPad Air had been fitted with an 11" display instead of 10.9", I probably would have purchased it.
