Apple's online store went offline Tuesday morning and was replaced with the familiar "We'll be back soon" notice. Since the notice often times leads to a new product launch or upgrade, Apple could be updating the site with its traditional Tuesday morning surprises, and some people are speculating Monday's iTunes 8.1.1 update is related in some way.
Apple also recently tipped its hand when the company accidentally published a Web page showing an updated Xserve running Intel's Nehalem processors, much like the new MacPro.
