Just check MacRumors front page by time to time. Notify me is quick way too but I'm not sure how well it works (some news like new 17" MBP came 4 months late for my e-mail)
cool I'll stick with checking the forum
Why can't/won't apple put a date on the release? Its only a few days till sep really - surely they aren't still writing the last few lines of code - they must know!
