I hate that everyone is pushing 3D with shutter glasses, its an obvious choice for the companies (since you'll be paying through your nose for the glasses). Sucks for consumers considering your $2000 3d HDTV is going to end up being closer to $3000 once you go out and buy 4 sets of glasses to go with it.
With DLP technology, they should be able to polarize the color-wheel to allow viewing with non-powered glasses. The tradeoff would be that you need to buy a non-depolarizing screen (silver screen). Either way, a 1080p/120hz/3000lum projector should be on its way soon, although 3D Blu-ray movies will only be 720p.
