What's the general consensus on whether or not there'll be a fall update to the MBP line? There's word that ATI 5000 series drivers for the Mac are in the works and I'm basically holding out for a decent GPU to appear in the MBP before I upgrade. The current offerings are probably the worst in years. There's also that 2.8hhz Core i7 chip expected to show up in portables. Any chance the two could come together in a refresh this sept-oct?
