Kreylos compares his predictions for the future of Kinect development to that of, surprise, the iPhone. When developers want to develop for a multitouch system like the iPhone's, they can either use a basic, free toolkit, which gives basic results; or they can expand on that on their own initiative to get more complex and interesting results (which requires more work); or they can use a third-party toolkit which has more advanced built-in functionality, but which may cost money. Right now, without the official Microsoft SDK, developing for the Kinect is hard. Really hard. But if Microsoft really makes an effort with the SDK, and includes all the tools a developer might need--including skeletal mapping to see the position of all of your limbs, voice commands, and gesture recognition--we might see some very impressive apps coming from what's now the Kinect hacker scene. Official developers, we assume, already have access to all of this stuff, but those are big international companies. Microsoft needs to think about the little guy, too.
