Anyone on here will be quick to tell you that Apple retail employees aren't really privy to release dates, and if they somehow become privy, NDAs would threaten their jobs if they told you.
However, on an unrelated point, the employee was wrong about the education discount not applying to the Macbook Air. You can get the Air for $1699 with the education discount.
I understand that they aren't supposed to say anything whether they know or not and the employee made it clear multiple times that he could not disclose any information or rumors of new products. The way the question was asked about the discount on the new Pro with the discount was what got him.
Employees at Best Buy and at the Apple store both said the Air was not subject to the discount. The reason I asked the Apple employee was to see whether or not the two stores were on the same page.
