Technology Evangelist interviewed Jim Denney, VP for Product Marketing at TiVo, at CES and the video is on their site. It is a really good interview and he talks about the future of the Series3, indicating MRV & TTG will come later this year, among other things like TiVoCast, TiVo Desktop 2.4, etc. It is about 16 minutes long, and worth watching.
Since it is hosted through Brightcove, it would be nice to see it added to the content available on TiVo.
