Yup, wait for the technology to ketchup first. Right now it's like 2002 getting a HD tv and it's only 480p. Full Aperture format is the only way to go due to aspect ratio. Also, the amount of data needed to transfer the picture to each home is ridiculous. It's taken well over a decade to upgrade systems for 1080p!
