Apple TV 4K may be grabbing all the headlines, but don't sleep on Roku. The AV accessory company is apparently prepping a new streaming stick capable of porting through 4K High Dynamic Range (HDR) content, and at a likely cheaper price than Apple.

The new 4K HDR Roku Streaming Stick+ was uncovered by Zatz Not Funny thanks to "a trusted source," though we don't have official word from Roku yet.
