I called Best Buy Mobile to ask whether they'd have the phone on the 8th. They said yes, certainly in stores. Agent did advise me to check the website periodically beginning on the 6th or 7th. Hey, you never know.
Not necessarily true. I was able to get my OG Droid before the actual release date. I'm not sure that you'd be able to order online, but you can most certainly try to get an employee to sell you one in store before release!
