The new $99 Apple TV, announced on Sept 01, had always listed on Apple Store with a shipping date in September. Apple yesterday started charging for those who pre-order the Apple TV. But some customers also received email from Apple informing that their expedite shipping charge is waived due to a possible delay. And on Apple Store, Apple TV is now listed with expected ship date in 2-3 weeks.
There is no words from Apple on what’s happening. It could be a product delay, another possibility is Apple TV is selling so well that Apple is running out of initial stock.
