Yes, and I think that's how things are going to go down anyway: The best televisions this year just happen to support 3D; it's something that the manufacturers are throwing into the top of the line sets and the second-tier sets as sort of a built-in upsale prompt. Next year, figure that'll percolate through to the second-tier manufacturers and the third-tier sets for the top-tier manufacturers. And so on. Eventually it'll just be there, whether you want to use it or not. Most of what it is is software, so it will likely follow the same path that other software features follow, introduced one year in a few models, then the feature becomes more and more common, and then later it is a standard feature.
The question will probably not be whether to get a 3D set or not; but rather whether or not to get the 3D glasses that you need to view 3D on the 3D set. Those cost extra, and will likely not be packaged in the sets, since they represent significant cost per unit.
