Several reports are coming in that Apple will be refreshing it’s MacBook Air Sandy Bridge line very soon. It is very possible Apple is planning to release this in time for the OS X Lion release, which Apple has stated will be in July.
The new MacBook Airs will feature the same sizes previously, but will include the new Sandy Bridge Core i processors. We’re assuming that they will only include the dual core i3 and i5, but it is possible that Apple will throw in an i7. However, in the past, the Air has been it’s lower cost computer, and I would think Apple would like to keep it that way.
