Roku is already working on its next-but-one streaming box. In an interview, a mover and shaker at the gadget-maker revealed the Roku 6 is already in the works, despite only just releasing the Roku 4.
Asked if the Roku 5 was being worked on, Lloyd Clarke, director of product management at Roku, replied: "Yeah, and the one after that too."
So what can we expect from the next Roku box? Clarke said it will quicker to serve up what we're looking for thanks to improved "surfacing content" speeds.
"We find that customers are happier when they stream," Clarke said. "And the way they get to stream more is if they get a faster path to what they're interested in watching. We're working on a number of things to shorten that."
It'll do this by making videos start faster, and by shortening the number of steps it takes to get to a specific channel.
The Roku 4 was released in October. It's the company's first box capable of streaming in the 4K resolution, with four times as many pixels as high definition.
Last week, Roku announced its first 4K-capable TVs, though they're only on sale in the US.
