Apple is very very secretive about release dates. They will say "OSx Lion will be released around July" but they never say "New MBA will be in stores July 22".
Virtually everything is pure speculation.
I love Apple products, but this is why I wish a true competitor would emerge. IF there was a worthwhile competing product to Apple's lineup then their customers would simply choose another brand if the highly anticipated Apple version didnt come out when we wanted it. But as it is, Apple is too far ahead of the competition so we have no choice but to latch on to the (mostly) made up words of analysts and rumor sites.
(BTW. I get it, Apple doesn't owe us anything. I'm just saying that the more we rely on Apple in a business sense, the less fun it is to rely on rumors for factual information. Secrecy works in building buzz among consumers, but for businesses its hard to consider a move to Apple products when theres so much secrecy about what their product cycles will be. I know a lot of companies where the whole iPhone 5 delay has caused a lot of problems due to contract renewals, phone replacements and angry business end users getting put on hold until Apple tells us what they are planning.)
