Not surprisingly, Apple has taken its web-based storefront offline to update its virtual shelves with new listings for a new range of MacBook Air laptops, OS X Lion, and perhaps other goodies.

Already confirmed by the company’s chief financial officer, Mac OS X Lion is scheduled to arrive in the Mac App Store today.

It will be accessible to anyone running Mac OS X 10.6.8 (Snow Leopard) on their Mac and it will be priced at $29.99 as an upgrade from the current Mac OS.

Now that we can finally put all the Lion-launch-date rumors to rest, the technical specifications for Apple’s next-generation of MacBook Air computers have just been leaked.

Without fail, Apple will begin listing the new configurations on its online store as soon as the venue is back on its feet, ready to serve technology-hungry Apple fanatics.

According to a person who is allegedly privy of the new systems, these new MacBook Air configurations will include faster Sandy Bridge Core i5 and i7 processors (up to 1.8 GHz), double the RAM (4GB) and NAND Flash storage (up to 256GB on the higher-end versions), and Thunderbolt connectivity.

No word on whether or not the new MBAs will also feature backlit keyboard, as previously speculated, but we should find out soon enough.

What’s strange is that Apple seems poised to upgrade only its ultra-thin notebook line, but not the Mac mini and Mac Pro desktop computers.

Also worth noting is that the White 13-inch MacBook may be phased out soon, should they decide in Cupertino that it’s not worth upgrading to Sandy Bridge.

As with the aforementioned systems, it shouldn’t be long before we have confirmation about which Macs are getting pimped out, and which aren’t.

In the meanwhile, you too can speculate in the comments.

What new announcements do you think may arise in addition to the already confirmed Lion and MacBook Air refresh?

UPDATE: Apple's web store is back online with pretty much every rumored announcement confirmed. Visit mac.softpedia.com for the full details on every one of them.
