It looks like the 3.0 banner still shows an iPhone with a silver bezel. Would that be a hint that, a) the black bezel rumor isn't true or, b) there will be no new iPhone announcement after all?
Any banners that mention or reference unannounced products get covered in black until after the keynote. All banners will have pictures of current hardware or things we already know about.
And to everyone hating on the idea of an App Store for the AppleTV, multiple sources are reporting that it's going to happen. That WWDC developers will get an AppleTV SDK and that it will go live sometime in the fall.
And I don't get why people keep asking for hardware updates at WWDC. It's not an event to show off what's new and hot. It's an event for developers.
