I think people didn't understand the OP, Im also holding off to buy a new Mini, and actually think the chances of a refresh coming within 6 weeks, at June's WWDC, are rather high: we're talking about the top of the line / higher-end Mini which is still Intel-based and has yet to transition to AS.
There's a pattern here, Apple refreshed all the lower-end, less ports, lower GPU powered Mac's: the MBA, the 13" basic MBP, the lower-end Mac Mini's, while leaving the top tier ones on Intel. When the new higher-end MBP's, iMacs, etc. get introduced, with an M1X, M2 or however Apple calls it, Im sure the higher-end Mini will transition from Intel as well.
Remember that Apple said they would transition the whole line up within 2 years. We're 1 year in, the higher-end Mini, along with the higher-end MBP and iMacs, are all still on Intel, a refresh to the higher-end Mini is coming, and will hopefully offer the expected benefits: beefier GPU, more I/O ports/connectivity, just like it does now on the rather old Intel model they're still selling.
If Apple weren't thinking on having a higher-end AS Mini, they would have just discontinued the Intel model last November.
