Earlier today Apple had announced the third generation Apple TV with an all new UI and 1080 p high resolution support. Apple offered the new set top box for just $ 99 and the pre-orders began immediately and the shipping estimates initially was March 16th. Now it seems according to the official website that the shipping estimates have now slipped by a week or two.
It clearly indicates that Apple has ran out of initial stock for launch and now is going through shortages of Apple TV. Now the official page claims March 16-19 as the shipping and not delivery dates.
Rather surprisingly the delivery dates for the all new iPad is still March 16th. Its almost obvious that the iPad must have received much higher orders than the Apple TV but still the pre-order site is showing the constant date.
