A new report corroborates earlier indications that Apple will begin production of revamped MacBook Air notebooks this month, while also adding an unverified tip on a high-resolution iPad 3 reportedly coming later this year.

Per Reuters, Apple will begin selling the new MacBook Air in late June with an initial shipment of 380,000 units.

According to the Economic Daily, when shipments of the new MacBook Airs are combined with shipments of the existing model, 460,000 units are expected to be produced this month.

Over the weekend, one tipster claimed that revitalized MacBook Airs would arrive this week, but eventually revised his story to suggest that Apple would actually begin carrying unlocked iPhone 4s at Apple Stores in the U.S.

The report also claimed that Apple will launch the iPad 3 in the fourth quarter with “image resolution 5-6 times higher than iPad 2.” But, it should be noted that the rumor appears highly unlikely and is reported here for the sake of completeness.

While numerous reports of an upgraded iPad 3 with a doubled resolution of 2048 x 1536 already exist, the resulting display would have four times the amount of pixels. Various sources have also hinted that the iPad 3 will not arrive until 2012.

Apple has reportedly begun certifying components for the iPad 3, but component makers expect the device to come out next year.

Stay tuned for additional details as they become available.
