The Apple Store is still down. Everything else has been updated, even the iMacs and the Macbook Air that most people had considered were not getting an update today.
It would make sense for a silent update of the Mini to Kaby Lake standard. Bear in mind the clue here is the iMac 21.5" which got an update to Iris Plus Graphics 640 at the base level. This is the 15w Air class CPU which I expect will find itself in the refreshed MBA and base non-touch-bar 13" Pro.
I still think the Mini is going completely 15w CPU. Probably not something they want to mention in a keynote.
