This article is making the rounds on the internet so we may as well throw in our two cents. I think there is a lot of confusion and misinformation about HDTV in general and 1080p specifically, and this piece in particular has a lot of both swirling around it.
First, let's address the section I've seen quoted most often in forums (usually misinterpreted or presented alone with no context). "How about Blu-ray and HD-DVD? If either format is used to store and play back live HD content, it will have to be 1920x1080i (interlaced again) to be compatible with the bulk of consumer TVs. And any progressive-scan content will also have to be interlaced for viewing on the majority of HDTV sets."
What does that mean? If you have a player that outputs only in 1080i (like the HD-DVD player Ben reviewed) and/or a 1080i TV, you will see ... you guessed it 1080i. Not incredibly complicated or shocking, just something I've seen people go into a frenzy over and suddenly believe 1080p is as real as the boogie man, Easter Bunny or gas that costs less than $2.75 per gallon. Trust me, 1080p is real, but you have to be careful about what you're getting.
As it stands, this piece is at best half done, definitely outdated and somewhat inaccurate.
