Pretty excited about the upcoming announcment. My 5 year old MBP is a little creaky these days so I've been waiting for this refresh before plonking my money down on a replacement. The Light Peak stuff is pretty cool, I'm looking on this laptop to be my main desktop machine too, so I was looking at USB3 ExpressCard adaptors. Although from reading the stuff on MacRumors, it appears the ExpressCard is no more.

My only concern is the combined nature of the LightPeak/DisplayPort connector.

EDIT: I stand corrected, the ExpressCard slot is intact.

EDIT 2: It appears you can daisy chain lightpeak devices and DP devices at the same time.
