The clever remote control audio out capabilities introduced with the Roku 3 will be making their way to the Roku Streaming Stick according to today’s FCC filing. Despite new MHL-compatible partners, we can’t imagine Streaming Stick sales have been significant… as it’s often cheaper and always conceptually simpler to bring “Smart TV” capabilities to a HDTV via a set-top. And we suspect Roku would be better served by integrating their platform directly into the television, as Vudu once attempted, should they find any takers. (Thanks Brad!)
