iPad 5 possible in April/May?
Not based in this sale. After all it's the iPad 3 they a clearing out. An item that has been off sale for 4-6 months now. They can't return them to Apple so they a trying to dump them anyway they can. Nothing more or less.
Now if they did the same to the iPad Mini or iPad 4, that might mean something
