WWDC 9-13 June

I was checking out the WWDC pages at the Apple site and I noticed this:

Create Engaging Media Experiences
The iPhone SDK provides an amazing lineup of technologies for developing media-rich mobile applications and cutting-edge handheld games. Learn from Apple’s Graphics & Media engineers as they reveal the techniques to harness these technologies in the most efficient and sophisticated way possible.

• Animate your user interface so your application can provide the dynamic user experience expected on iPhone.
  
• Dive deep into the APIs to render interactive 2D and 3D graphics in real-time.
  
• Experience the features of the built-in frameworks for playing and recording audio.
  
• Understand how your application can support video download and playback.
  

Which suggests that Apple expect developers (those they've let register that is) to make use of audio and video capabilities.
