At the MacWorld Expo keynote on January 6, 2009, Phil Schiller announced a 17-inch MacBook Pro with unibody construction. This version diverged from its 15-inch sibling with an anti-glare "matte" screen option and a non user-removable lithium polymer battery.

On April 13, 2010, the MacBook Pro saw another update. Intel Core i5 and Core i7 CPUs were introduced in the 15- and 17-inch models, while the 13-inch retained the Core 2 Duo with a speed increase. Next update? MacBook air took more then 12 months way longer then it's other previous update cycles. Update can range from now till anything before the iPhone 5 updates. Will it be updated before the iPad 2 or after? iPad 2 to be updated most likely March/April 2011.
