Vizio announced their new line of 3D TVs recently with a big surprise.  The new line of TVs don't use the big and bulky active shutter glasses that you find with 3D TVs in stores now but "passive" glasses that you find in the movie theaters.  These new "passive" glasses are inexpensive compared to the active shutter glasses ($199) and also are smaller and lighter.  So now you can get enough glasses for everyone to watch 3D without emptying your wallet.  Vizio has a 65" XVT3D-series set that is available right now for $3,700
