Final Take on 3D TV

I feel that 3D TV is hear to stay, but it will be more of a niche audience for some time, until pricing and content are widely available. You have to remember that all new tech takes awhile to make inroads. Also, manufacturers and content providers need to keep in mind that most consumer just purchased new HDTVs as a result of the recent DTV Transition and asking them to fork out more bucks to upgrade to a 3D TV now is too much to expect, especially in the current economy.
Also, another move in the industry is the possible introduction or Ultra-High Definition TV (also refer to as Quad Resolution, 4K, or 4K x 2K) which creates another TV product category that consumers could be faced with in the next several years, at least for screen sizes 65-inches and larger.
However, before your start to panic, keep in mind that, just as with 3D now, unless TV broadcast bandwidth is increased, a new compression alogrithm is worked out, or a new disc format is created, actual Untra-High Definition content will be almost non-existent for some time, so almost everything you would e viewing on an Ultra-HD TV would simply be upscaled from current 1080p content.
What will happen going forward is that 3D will be just another feature offered on and increasing number of TVs that you can advantage of or not, in same manner as the increasing number of TVs that have internet connectivity and media player functions. When you shop for a TV, just make sure it has the features you want, whether its 3D, internet streaming, media player functionality, easier-to-use onscreen menus, or Ultra-High Definition resolution (when that comes out).
