I have a 2019 imac and this is very disappointing!

Are they excluding ALL 2019 iMacs?

From what I can tell you need a Vega GPU to run it and the 2019 iMacs with the Core i9 could be configured with a Vega 48 GPU which should support Metal 3

However the default GPU on the 2019 iMacs was either a Radeon 560/570 or 580x which would not support Metal 3

I found the WWDC slide outlining hardware support.
