I ordered my second new MBP Core i7 Wed May 5th. Earlier today I received the email saying it shipped with an arrival date of Wed May 12th, just one week from order to arrival. That's faster than the one I'm typing on now. I'm impressed that Apple is keeping up on the demand.
Two days before I ordered mine the web site said ships in 5 to 7 days for the i7, i5's were just 1 to 3 days. So perhaps that's an indication of the popularity of the Core i7. Anyway when I revisited the site to place my order two days later, the ship time had dropped to 2 to 4 days. Mine shipped in two, a very impressive performance by Apple...
