Apple Pro has some mixed sources. The leaks about the unibodies were rights, while the one from Appleowner.com were all falses (All aluminum Macbook lid, supposedly Macbook video). He also claimed that the Macbook event would come maybe in november if we are lucky (somewhere in his blog posts, don't know if it was posted here). Looking at Appleowner, there's nothing about a 15'' Macbook Air. Looking at how a lot of recents rumors become true (except about the introduction of the desktops) I wouldn't call fake too fast.
