Mac Rumors:  Steve Jobs stated in an email reply that AirVideo Streaming is coming in 2011 for Safari and third-party applications.

This is a welcomed news as many where left wondering if Apple had plans to enable AirVideo for third-party applications through an Xcode update.

The current AirVideo API are private and can’t be used by non Apple developers.

Jailbreaking developers have written a small hack that proves that AirPlay can technically stream third-party video to the AppleTV2.  So do not despair to get AirVideo from your prefered application sometime next year without resorting to Jailbreak your iDevice.

I personally think that the new AirPlay for third-party application will be made available when the iPad2 launch in 2011.  Maybe the iPad2 will have some exclusive game video to AppleTV integration?  I speculate that such a feature might require a new processor that can handle encoding of output video on the fly for proper streaming to the AppleTV2… maybe through a multi-core CPU design with dedicated screen output to mp4 transcoding?
