Can I jump on the bandwagon here. I was about to post a similar thread asking more generally what ship dates are for iMac's, MacBooks and MBP's.
I've noticed quite a few 15th September ship dates which is coincidentally (or is it?) the date my MacBook is due to ship. I'm curious as to whether the concentration of shipping around a couple of days indicates a possible bump to the MacBook. It's unlikely, but I can dream.
Anyway, for the record I ordered a 2.0 white stock MacBook this morning (middle of the night for you Yanks) and my ship date is the 15th September.
