sonos ace ultra

The forum thread about the Ace Ultra starts out with ‘Sonos Ace Ultra ships on September 29’, I don’t think this community has any contrary information. 

There are some posts on r/sonos where users have received shipping notifications earlier this week.

This user says they received delivery of their Ace Ultra on Tuesday:

Keep an eye out for the tracking email, or check the order under your Sonos account online to see if/when the order status updates.
