Compounding previous reports of global stock shortages of Apple’s slim-line MacBook Airs, plus the rumoured product numbers we saw the other day, now some leaked pricing supposedly points directly to a new MacBook Airs.

9to5Mac reports that it managed to get a sneaky peek at the pricing for the previously leaked SKUs, which confirms that they are indeed for four new MacBook Airs in a pair of spec levels for the two screen sizes, 11 and 13-inch.

The site also has it that the new MacBook Airs will come packing the new, faster Wi-Fi spec, 802.11ac, with supposedly some new Airport and Time Capsules on their way to support the next-generation wireless standard too.

Who knows whether all this is true or not — treat with scepticism for now — but it certainly looks probable. At least probable enough to warrant delaying a purchase of any new ultrabooks until after Apple’s keynote at WWDC on Monday evening next week. [9to5Mac]

Almost a full week before its annual developer’s conference is set to begin, Apple has already started to move into San Francisco’s Moscone Center.

Half of a giant Apple adorned the side of the Moscone Center Tuesday evening, abandoned mid-construction. With no crew in sight, we suspect the other half will join it Wednesday morning.

Inside crews have already covered the back wall of the lobby with a giant multi-colored WWDC banner.

Many other rolled up signs and banners currently litter the lobby.

WWDC is set to kick off early next Monday morning. The annual conference focuses primarily on Apple’s mobile and desktop software: iOS and OSX. Apple has already acknowledged plans to announce new versions of both at this year’s event.

Tickets to this year’s conference sold out in under 2 minutes.

While definitely a software-focused event, WWDC has also been the stage for many notable product announcements. Last year, for instance, the company announced its first MacBook’s with Retina displays.

Apple is rumored to be potentially refreshing that line of computers during WWDC this year.
