WWDC 2010 Is Sold Out

I wonder if the Macintosh developers conference will break away from the iPhone+iPad developers conference in the near future.

The lack of a Macintosh Apple Design Award this year hints towards this becoming (or already being) an iPhone+iPad conference.

Could a split be on the way?

Or, does this hint at Apple only caring about the user experience on its mobile devices from now on and the Macintosh becoming just the tools with which to create content and Apps for its mobile "consumer" (or "consumption") devices.

If so, where does that leave developers of tools and "Professional" Macintosh Apps?
