Images posted to Flickr show the crowds inside of the Scottsdale Microsoft Store, as well as a look at the store's layout. There are also images showing the line of people we saw in a YouTube video we covered earlier extending far outside the mall.
The images were posted by Flickr user "Microsoft Store," who is as near as we can tell the same "microsoftstore" that posted the video to YouTube. You can see much more of the Microsoft Store in the Flickr stream.

The line of people waiting for the store opening extends far outside the mall.

Thanks to Scott Knaster for the heads up via Twitter.

I’ve a sneaking suspicion that “Microsoft Store” and “microsoftstore” is working on behalf of Microsoft, mainly due to the shots taken before the store’s opening. Well, and the user name.
Be that as it may, that is a seriously ling line of people. I am impressed. If MSFT can do it again without the lure of a new OS, they could have a hit on their hands.
