Few days ago, some sources pointed the iPad 3 could be coming in the early March. Now, more sources saying the major retailers are having iPad 2 supply shortages which would probably means iPad 3 is coming.

Normally, those retailers can get the iPad 2s very easily when it is nearly out of stock. Now, it’s limited.
Sources reported that the iPad 2 3G version is the popular one. In UK, Carphone Warehouse and Orange UK are having iPad 2 3G version shortages.
