Wow, EnTerr, don't ever think your contributions go unappreciated.
The PS4 just got 4k turned-on for video playback this year. With all the respect in the world to Roku, the PS4 is running about $400 right now with the traditional profit margin of consoles where they get no margin or take a loss...so the hardware is just a teensy bit better. If nothing else, the PS4 does have an 'off' switch for a reason...the lights dim when heavy computation is going on.
At least my personal initial reaction to 4k was, "this is good, but I wouldn't pay for it." 1080p is still awfully darn good, and 4k just doesn't have the wow factor.
Last but not least...the content that really supports it, is limited. Like, content that uses the full resolution and color depth. Sure, there may be content that will use all the pixels, but was it natively filmed that way? All I have is maybe some CGI movies and if they decide to do another Blue Earth.
