IMO the reason they are all going with shutter glasses is they think they will make more money that way. They will all try to come up with proprietary shutter glasses that you have to buy from them at big markups. They know that the glasses will be easily lost or broken and people will keep buying more and more of them. With polarized everyone could just go to Walmart and pick up 10 pairs for $20 or so if they were having a bunch of people over, or whenever they needed more. Why do you think they can't do 1080p with polarized? I thought there were a couple of them at CES?
