Actually it shows 'Your order has been sent to Google Commerce Ltd.'

Play shows 'Completed'. Which I assume to mean "the order has been successfully placed, you'll get the product". If I'm really that unsure I can click on 'info' and be taken to the Google wallet transaction.

I truly cannot see why this is confusing to anyone. Yes it's crap that there is no announced shipping date.

I've seen people get so ridiculously worked up over this, you've pre-ordered it, just be patient. It's already stated that you'll receive an email with a tracking number when it ships. Relax, it's coming.
