With the new Amazon Fire TV and Apple TV getting so much attention, it’s about time that Roku show off its own next-generation digital media player. Reports of the device have been popping up for a while now, and while we still don’t have any official information, a recent filing with the FCC suggests that the device could be launching really soon. Known as the Roku 4400X, the device has been submitted to the FCC for approval, which lends weight to the rumors that the Roku 4 will be launching on October 1st.
