Shortly after one unnamed iPad model was spotted at an EEC listing, four new iPad Pro models were spotted on a Chinese user manual. Even though Apple has removed the models from the manual, that effort wasn’t enough because both display sizes and model number details have come forth. The models are listed as follows.

As for the display sizes, it looks like Apple will use the same 11-inch and 12.9-inch variants just like it did back in 2018. What this means is that the rumored 12-inch iPad Pro might not materialize, and for those that are disappointed, this move will actually work out in Apple’s favor. That’s because the existing iPad Pro models resonate a winning formula in place, so why would Apple proceed to release a newly designed tablet that would require more resources to make? Instead, employing the same design with upgraded internals and you’ll have fewer resources to utilize while selling more units.
