There will be some talk about xCode, Metal, App Store policies (in light of all the gubmint and lawsuit hogwash), and Craig Federighi will resist cracking any jokes since he doesn't have an audience of worshippers to preach to.
Hardware may talk about the M1X/M2, although I think Apple has "shot its wad" as far as announcing Apple Silicon prior to a piece of hardware it goes in. Thus, a new chip does not get discussed unless there is also a new Mac to shovel it into.
That said, the outlier is the new MacBook Pro.
I cannot think of any other hardware, other than a new iMac Pro, but it seems that might be announced alongside new MacBook Pros in the fall.
