A new channel has just popped up on Apple TV for its WWDC 2013 Keynote, meaning that a livestream of the big event will be available for viewing there -- just like last time. The HD stream will kick off at 10AM Pacific time, and there's a chance you'll see it on Apple's Events page as well, if history repeats itself. You can also catch past extravaganzas at either spot (see the More Coverage link), and naturally, we'll have a full liveblog of our own -- so there's no chance you'll miss any of the fun.
Update: The WWDC 2013 Keynote livestream link has now arrived to Apple's Events page as well (at the source, below), though you'll need to be on Safari 4 with OS X 10.6 or Safari on iOS 4.2 at a minimum to watch it.
