You likely won’t see anything until everyone gets one. The Clockwork shipments seem to run in a quarterly cycle, i.e. every three months. This has not been confirmed, it’s just a pattern that we have noticed in the community. I ordered the GameShell last year, and I am waiting on the console now.
You only get two communications after the order:
The order notification
The shipment notification to track the order
The 90 business days warning is definitely not an estimate, it is an FYI. It does take that long.
