Apple is preparing to announce its next AppleTV in June (see the link). Rumors abound that Roku will be upgrading their line of media players soon. Others have introduced 4K (aka UltraHD), but you'll need to upgrade your TV to experience it, and there's limited content. Google, Amazon and others continue to innovate and deliver. My suggestion is to wait until July at the earliest before you pull the purchasing trigger. If you can't, Roku 3 is my favorite.
