I doubt it will fail even if people don't care simply because once the early adopter premium is over the cost difference is not that huge and unlike 3D there's really no downsides. Checking my local price comparison site here now in Norway there's 84 TV models with 720p, 7 models with 1080i, 445 models with 1080p and 253 with Ultra HD. If I restrict it to 50"+ models UltraHD is already in a majority (188 vs 176). About 4 years ago I bought a 60" 1080p LCD, I see now you can get a 58" UHD LCD for 20% less. Am I going to run out and buy a new one? Hell no, but if it needs replacing they're already at the prices you paid for a 1080p screen five years ago. With UltraHD Blu-Ray launching before Christmas there'll actually be high bandwidth content too, not just Netflix stream. Though I'd rather wait a couple years more until I'm sure any TV I buy will be compatible with the new features like HDR and Rec. 2020. Then again, like computers there's always something better coming.
