The Galaxy Tab 10.1 was released in June last year, but they announced the product in February and redesigned in in March. It was grueling waiting and waiting.
Perhaps Samsung is keeping it closer to the chest this time. Wants to get the product closer to a finished stage before unveiling it. Perhaps it's so awesome they don't want to tip off the competitors too early.
Hopefully it's a real product that gets released by June.
