I wonder if they’ll tier the RAM like they did in 2018. 8GB for the 1TB (or higher?) and 6GB for all lower storage options. I hope they don’t do that but knowing Apple, the 2018 iPad Pros should have all shipped with 6GB of RAM and the 2020 should have been bumped up to 8GB.Refreshes are an OS issue, but more RAM helps, esp. as Apple updates the OS restrictions in later iterations.
My guess is it will have 8 GB RAM.
Yes, it will likely be USB 4 with Thunderbolt, and that is a very big deal.
