According to people with proven track records who would be in a position to know, the new product launches are set to occur later this week. Specifically, one person said the products would be released on Wednesday at 8:30 a.m. Eastern.
The latest details align with what AppleInsider was told earlier this month, when it reported that new MacBook Air models with backlit keyboards and Thunderbolt ports would launch the week of July 21.
The rumor mill had Apple releasing its new OS and notebooks last week; however, that date passed with no sign of new product updates. The WSJ's AllThingsD has also predicted that the release will actually be this week. When criticized for guessing, Kara Swisher stated, "We're not guessing. We never guess. You'll see."
Apple has only officially announced that Lion will be released in July.
