I believe 3D is here to stay ... but not in its current form because ANOTHER way of doing 3D WILL come out in order to, once again, sell more TVs.
Tube TVs were made to last 15-20 years. The 32" Sony I bought in 1995 and gave to my parents is STILL going strong. At the SAME time, I've gone through THREE projection-type sets just to upgrade to higher resolutions. Now I rarely hear of these flat TVs lasting more than 5 years before some new standard or whatnot is announced ... or the controller hardware dies.
3D standards will get finalized in a couple of years and those caught with the " losing " standard will have to upgrade or do without. 4K will be out a couple years after THAT and then a 3D standard for THAT and so on.
