Several sources, including self-professed leaker Jon Prosser, have claimed that there will not be any hardware releases at WWDC this year. With the Apple store still being up as of this writing, it is a fairly safe assumption.
As those who followed the Apple WWDC keynote saw, there were no specific hardware unveilings made, just a general announcement that Apple is moving the Mac (over a two-year period) to their new, newly-branded "Apple Silicon".
Well, they did unveil an iPad Pro re-packaged into a Mac Mini development system. It won't be sold to consumers, and it uses the same A12Z Bionic SoC as the current iPad Pro, but supporting a much heftier 16GB RAM (compared to just 6GB in the iPad) and half a TB of flash SSD (plus additional I/O ports; video out included obviously... )
