9to5Mac cites their "favorite Apple source" who claims that Apple will be delivering minor updates for MacBooks and MacBook Pros at WWDC. The source speculates that this could involve 3G or speed bumps or battery changes, but this is entirely speculative. Also expected are updates to Apple's Pro Apps including Final Cut Pro, Aperture, Logic, and Shake.
Such updates at WWDC would be somewhat uncharacteristic for Apple who has not historically focused on these products during the developer's conference. Looking back at previous WWDCs, Apple has focused on iPhone, Mac OS X and Mac Pros/PowerMacs at the annual event.
WWDC 2009 takes place in San Francisco between June 8th and 12th.
