I'm not buying it.
Look, perhaps the authors at Android Central are new to making purchases at BestBuy - who knows? However, I've got a long-standing history of being able to secure high-demand items at BestBuy and have a pretty good understanding of the intricacies and nuances of how their system works. To date, there hasn't been a single 'must-have' item sold by BestBuy in the past decade that I've failed to secure, if I had desire to purchase it. Mind you, all of this has been done without bots or external resources (e.g. page alert sites) - just an understanding of their system.
I've been transparent in my interpretation of the current situation and expect that the product will shadow drop at some point today. Afterall, their wording in the announcement yesterday about 'after 8 am Central' was almost certainly intentionally-ambiguous. That being said, I would have been foolish to NOT try at 8 am Central, in the event that they fast-played their hand.
Have patience, padawan.
