This is true in principle. But the NTSC system still has much too little
color bandwidth. Color of half to two-thirds the luminance would
be acceptable. 

And most of the world won't be looking at NTSC quality, or a little
better, for much longer. Japan certainly won't.

According to today's San Jose Mercury, Bush just killed DARPA HDTV funding.
He also wanted to drastically cut back the rest of DARPA.
