We will not be attending the Apple Event that starts in 40min in the Apple headquarters at Infinite Loop, but a couple of sites that provide excellent live blogging will be there.
Every time I root for live video streaming for such events. Apple films these events anyway, but only releases the video after the event.
The highlights of rumored new things to be found in the new Apple laptops include, all aluminum cases (brick), two NVIDIA GPUs in MacBook Pro, glass multi-touch trackpad with no buttons, and possibly (but unlikely) a sub $1,000 MacBook.
As reported earlier the Apple Store is already down.

Anyway to get the news about the new MacBooks as early as possible visit either one of the sites below:
