Apple has taken the online Apple Store down just hours before today's WWDC 2012 keynote. If you attempt to visit the Apple Store right now you're greeted with the familiar "We'll be back" message (the yellow sticky note it used to be written on has been gone since the launch of the new iPad back in March):
While there have long been rumors that Apple would be announcing updates to several of their Mac computers, this all but confirms it. What it doesn't do, unfortunately, is confirm any of the details. That means we'll still have to wait for the keynote to see whether the new Macs will be getting retina displays, or whether they'll roll out an entirely new line of MacBook.
You can check out our WWDC 2012 page for more information, and for live coverage of the keynote once it begins. It's scheduled for 10 AM Pacific time (1 PM Eastern).
