Roku, the current market leader in streaming media boxes may be close to launching an updated device for the fall. Dave Zats  has been monitoring FCC fillings and discovered that Roku has filled new paperwork that indicates a new product and or update to the current line of products that will feature 4K video. Zats also cited the brief appearance of a 4K video channel in the UK Roku Channel store. Will Roku release a full new line of products so soon after the updated Roku 3? If they do will the company still stubbornly stick to the 1-2-3 branding. We will keep an eye on this going forward.
