Launched just yesterday, Comcast’s Xfinity 3D will be a new full-time 3D TV channel offering up a big mix of content from music and sports to movies and original programming. Xfinity 3D joins ESPN 3D, n3D and 3net as full-time 24/7 3D content providers and they kicked off their premiere with an NHL hockey game between the Montreal Canadiens and the Calagary Flames. After the game, Kings of Leon played it out from Germany. This channel reminds me of HDnet, one of the first channels to be full-time HD, before many others joined. Does this mean that more 3D channels will come out and be full-time?
