I personally wouldn't like to be an early adopter of a new technology (like HD DVD). I'll wait for 2-3 years to 3D technology to mature and stabilise. The manufacturers haven't reached a proper consensus as yet. For example, did you know that you can use Samsung 3D glasses to view Panasonic TVs & vice versa upside down? The manufacturers have admitted that there needs to be a better communication between themselves.
I'm expecting the next generation of TVs to come with a common technology, so that you can even buy cheaper 3rd party 3D glasses for much cheaper prices. Until, of course, all this is replaced by glasses-free 3D TVs like the Toshiba one.
