Again, not really.... By lately do you mean 'at the last one'? In 2016 they released zero new hardware products at WWDC... And then in 2017 they announced an updated iMac, an updated MacBook Pro, an updated MacBook, an updated iPad Pro, the entirely new iMac Pro and also the HomePod.but lately Apple has made WWDC to be software focused though
they have the rest of the year for other hardware announcements😊
So yeah, in 2020 there was no hardware (well technically there was the announcement that they would be releasing Apple Silicon Macs, though the specific products weren't ready), but in 2019 there was a Mac Pro and Pro Display XDR. WWDC is a fantastic place to debut new Pro hardware when it's ready.
