iPad 2 is expected to make its debut in the Hong Kong on April 15 (2011). There is this advertisement on the Internet that is giving them a clue about the aforementioned date. Unfortunately, it does not mentions anything about Apple or iPad 2.
All the ad shows is some Hong Kong people flicking and pinching the air. That is why I am skeptical about the release date and would advice my Hong Kong readers to wait for official Apple announcement. If you cannot wait for few days, you are free to spend as much as 11,880 Hong Kong Dollars (~$1550) which is the price of the iPad 2 in Hong Kong illegally imported from US.
