Actually...more than 15 major manufacturers already have plans to sell 4K HDTV units sometime by 2014 or 2015. There were plenty of them on display this past January at CES, and more are expected in 3 weeks at CES 2013. Those are major investments pointing to 4K HDTV becoming a reality. That said...4K as a broadcast medium is much earlier in the development cycle. It will also require a large investment, so it's simply too early to forecast if/when/how that will go.
