To be honest, there wasn't really a need for them. They dropped the price of the air, which is now probably on par or over the capabilities of the last MacBook. So the Air is basically now their entry level, basic 'MacBook'... back when they had the aluminum MacBook there lines between the pro and MacBook where really blurred. (Wish they'd put the same black bezel on the air though, that would look pretty darn sexy.)
