I don't know if it is truly a sellout nature rather than slow initial stock. My local BB still doesn't show any stock and have yet to get them. You still can't order the Pro from BB, but you can the Plus except it is backordered and has been since it showed up. The base is available and has been online, but still no stock in Florida. I tried asking a manger when their shipment was coming in, but all he could tell me is soon. This is the same response BB is giving in their forums. Weaknees was waiting for their shipment today. Amazon gets their shipment tomorrow, but had a few boxes initially. They are also handling the shipping for TiVo though. Walmart only shows the Pro, but ship to store by 9/2. I think either TiVo held back the shipment and/or waited to notify the vendors until after the announcement.
