Several sources indicate that the company plans to uncrate the eagerly anticipated updates to its MacBook Air line late next week. “The rumor sites are off by a week,” one source said.

AllThingsD weighs in on the MacBook Air rumors that have been circulating the past few weeks. They claim that the long awaited MacBook Air will arrive "late next week" according to "several sources".

AllThingsD says to look for an announcement Thursday or Friday and that the new MacBook Airs will sport a Thunderbolt port, backlit keyboards, and 128GB and 256GB storage options.

As we pointed out before, Apple will have to release OS X Lion at the same time or before the new hardware releases. So, expect OS X Lion sometime next week as well.
