This may look promising, buy there is a good chance that it's not. There is a new law that all TV programming has to be HD by 2009, this means that it will all be 16:9. Many shows right now are already 16:9, probably gearing up for a HD version.
Sorry, you're mis-interpreting the law.
It's that by 2009, all over-the-air stations must move to digital broadcasting. There is NOTHING in the law about high definition. The fact that high definition is being pushed at the same time is just the industry taking advantage of government regulations.
Basically, the industry wanted to move to HD, but sending it over analog would require a new standard. Creating digital TV also is something they wanted to do; but creating a new standard is expensive, and nobody wanted to foot the bill. So the government came into the picture and said "Well, you've got to create a new standard by 2006* anyway, so go to it." So they developed ATSC, the new TV broadcast standard. With it comes three basic resolutions: 480p, which is basically the same resolution we have now, only digital, 720p, which is 'Enhanced Definition' and is wide-screen, and 1080, which is 'High Definition', and is wide-screen.
Broadcasters can choose to broadcast only 'standard definition', 4x3 aspect ratio 480p if they feel like it. In fact, the new law only specifies that over-the-air broadcasters offer one stream of 'NTSC-equivalent quality' digital TV for free. They can charge for higher quailty, or for multiple streams. (DTV can have up to 6 different 'streams' on one 'channel'. Basically, PBS could show kids shows on one stream, home improvement on another, 'cultural' programming on another, etc. 6 streams is at standard definition, down to 2 at high definition. They can even have one HD and a couple SD, if they feel like it.)
This doesn't even cover the fact that the digital broadcast standard doesn't apply to cable or satellite. So they use completely different encoding schemes. But, for easy compatibility, they adopted the same set of resolutions as ATSC.

Yes, originally, old-fashioned analog signals were set to go away on Jan 1 of this year. It has been bumped later and later because the law says that analog will only go away if 85% of the population can view digital TV. That means both having local channels in place, and having equipment in customers' hands. Last I heard, we were nowhere near 85%, so I doubt even 2009 will happen.
