Weâve known for most of the month that Roku is preparing to roll out a new generation of streaming boxes. Now, thanks to Zatz Not Funny!, we have some new details about what the devices will be able to do, as well as how theyâll be branded.According to Zatz Not Funny! and a recent FCC leak, Roku may be planning to ditch its numbering system in favor of name brands. Rokuâs FCC filings appear to show new versions of all of its boxes, so Roku 1, 2, 3, and 4 would all be gone as brand names.The Roku Express and Roku Express Plus would take over the Roku 1's market, while the Roku 2 and 3 would be replaced by the Roku Premiere and Roku Premiere Plus, respective. The new Roku 4 would be called the Roku Ultra.Details on specs are still a little harder to come by, but Zatz Not Funny! reports that the new devices will support the HDR picture format.Most are speculating that the new devices will debut sometime this fall, in time for the holiday shopping season.
