So I just noticed this update from Google! It comes from their support page (I guess they are getting a tonne of queries right now).
You can view the message here: link.
Looks like mine won’t be coming until next week now – so much for being one of the first to get hold of one and getting this site off to a flying start. Looks like I’ll have some catching up to do.
The full message from Google follows:
In the US:
