Not hype, common sense. Technology is only going forward and 1080p is the next step over 720p. It will be 2015 before we see 2160p capable monitors come out and probably closer to 2020 before storage medium capacity (holographic disks) enables it to reach home video and processing power becomes cheap enough to drive that much data.
The problem is not what the monitor is or is not capable of. The issue is the infrastructure. Hell there are still non HD cameras in use that they try and upconvert in an HD broadcast.
Do you really think the same companies that have been draggind their feet to switch to Digital are going to run out and purchase all new equipment in the next 5, 10, or 15 years to support much higher resolutions? Remember the switch to Digital was supposed to have taken place years ago and it still is not final.
Remember stations are not required to go to HD they are only required to switch to digital.
Plus purchasing a TV now for something that may happen in 8 years is not an effective use of money. The technology will be better and cheaper by that time.
Purchase the TV that is right for you based on your needs and facts not on hyperbole or what you think might actually happen.
