Three MacBooks were said to be specifically mentioned, the 13 inch MacBook, and the 15 and 17 inch Pros. The MacBook Air was not mentioned, which leads to speculation that Apple isn’t going to bother with any upgrades (or new announcements) for that version. It is relatively new (and useless) after all.
By stocking up, resellers will be prepared for the upcoming back-to-school rush, while Apple will reduce their inventory and manufacturing as they switch over to whatever the new MacBooks will be.
Only 6-8 weeks to go.
