I'm not sure why it gives that impression. It's just an announcement for the live coverage they do of every Apple event...
Haha, I don't know why, I just say "check out the iPhone 5 announcement here!" and immediately thought there was some new information because we still don't know if it's an iPhone 5 or a 4S.
I had seen Ryan's tweet about it prior to the banner going up, so it didn't surprise me. But I can see how it could have!
Well, it is the 5th announcement about iPhone :)
I think it's more like they're invited to the event for sure.
