Since all the major players are bringing out 3D TV's (Sony, Philips, Samsung, etc) and some broadcasters (Sky Channel) are pushing 3d streams, I say, that this third wave of 3d technology has a great chance of catching on.
Even the Playstation 3 will or is supporting 3D functionality.
The thing to remember is that like surround sound, you don't want to have hours of non-stop surround sound or 3D. It would make you mad.
Even better would be 3D without the glasses, I reckons this is preventing full scale adaptation.
Unlike surround sound which you install once and poof it's there, you have to wear glasses, which is annoying for people who have towear glasses and also annoying for those who normally never wear glasses.

You forgot the taste and smell of war. The smell of scorched earth and the taste of mud in your mouth.
