Pretty much what above poster said, I think ESPN is canceling some of its 3D channels because there was no real user growth watching them, this is kind of same for the 3D technology, at this too few people actually have 3D playback to make it worthwhile trying to get their attention, on the other side of the issue you could be one of those pioneers who gets popular for the 3D videos, for me personally I am trying to figure out how to record PC games 3D and do that as the next step for my own channel, not sure if it will work though
