Not that this isn't obvious to most here, but it's quite clear to me that the next revision of the MacBook Pro will not have an optical drive. I would almost guarantee it. I just took delivery of a 17" MacBook Pro (purchased through my work) & it came with Lion pre-installed. There were no installer DVDs for the OS or iLife Apps. In fact, it can probably boot off of the Internet just like the newly released MacBook Airs.
