Apple's fall event is likely to feature two events this year, with the September event being dominated by the iPhone 14 line and the Apple Watch (this time with the Pro). There will be another one a month later featuring at least two tablets, the entry-level, cheap iPad 10 and the new iPad Pro.
According to Yeux1122, the usually reliable digialist,The iPad Pro's main attraction is the M2 processor, and it also has MagSafe wireless charging, the first addition to the tablet lineup.
In fact, last week it was revealed that the two Smart connectors on the top and bottom edges of the iPad Pro 2022 will be upgraded from "three" to "four" to power peripherals connected to Thunderbolt/USB-C ports on the iPad Pro.
The M2 processor is still a 5nm process, but Apple has redesigned its internal architecture with larger transistors, an 18% increase in CPU performance and a 35% increase in GPU performance.
As for those expecting a new shape change, I'm afraid we'll have to wait for the next generation of OLED screens.
