I wouldn't wait this far in advance -- new iPad Pro is rumored not to appear until the Fall. You can find $100 - $200 discount sales pretty regularly now on (check 9to5toys.com everyday), which makes me jealous as I paid full-price for my 2021 12.9" on launch day. It's worth it for the current M1, mini-LED model. And going from 11" to 12.9" is whole new experience IMO.
I was in dire need of an upgrade when I got the M1 iPad Pro. I knew they would go on sale eventually but for me, the 5-6 months of use was well worth the extra $150-200 spent.
