Maybe I missed the thread on this topic but
Daring Fireballs John Gruber has backtracked on Marble declaring it the codename for Xcode 4 (as some have speculated in the WWDC thread) instead of the unified UI for an upcoming release of Mac OS X.
"A few times since January 2009, Ive mentioned Marble, a secret UI design project at Apple which I believed was a new system-wide theme for Mac OS X. E.g.: my MWSF 2009 predictions, and my WWDC 2009 predictions. Ends up I was wrong about what Marble is and in fact, it was announced at WWDC 2010 this month. Its Xcode 4.
Also, he backtracked on the origins of iOS 3.2.
As for why this weeks new iOS 4.0 doesnt support the iPad, its simply a matter of timing. Apple wanted to start selling the iPhone 4 this month, June. The iPhone 4 required iOS 4. And it took less time for iOS to support only iPhones and iPod Touches than it would have to add support for iPads, too. I still believe that iOS version 4.1, planned for this fall, will be the release that unifies support across all shipping iOS devices.

So, basically, Gruber appears to know about as much as every other rumor monger in the Mac community.
