There's a big difference between a HDTV that:

Supports 1080i, but in reality needs to downconvert it to 720 or 768 to fit the screen resolution,

And a HDTV that has 1080 line resolution, and doesn't need to downconvert.

Actually, it's more complicated than that. Most 1080i HDTVs actually process two 540p images. To fit these alternating images on an HDTV with 768 lines requires a great deal of manipulation.

In a year, most new HDTVs 37 inches or larger will have 1080 lines. Thank goodness.
