Is 3D a Distruptive Technology?

Last year at CES 3D was everywhere. This year at CES there was very little mention of it.  One can buy 3D TV but most people that I know never turn on the function.  I personally have 2 TVs with 3D capability, but have never used it.

3D doesn't seem to fit the definition of a disruptive technology.  It is not something that emerging markets are using and the big players all have it, so it is not something that appears at this time to create new markets or displace established ones.

Is it just too soon?  Is 3D a sleeping technology waiting for the right application of the technology to make it really take off?  Ot is it just another technology that can be used when special effects are desired.

I was at the dentist the other day and he had a 3D machine that took a 3D image of your tooth.  Similar to a CAT scan for you mouth.  Maybe 3D is a niche market today, but will it break out into something bigger?

Are the requirements for special glasses holding it back.  Will glasses-less 3D catch on better?  Or do we have to wait for Google glasses to make 3D available for any and everything?

What do you think?  Will 3D be disruptive?
