Question about 1080i v 1080p

[emperoredals11]

I found this article, and was wondering how truthful it is.

1080iv1080p/

From the Article:

Short Version
What this all means is this:

• When it comes to movies (as in HD DVD and Blu-ray) there will be no visible difference between the 1080i signal and the 1080p signal, as long as your TV correctly de-interlaces 1080i. So even if you could input 1080p, you wouldn't see a difference (because there is none).

• There is no additional or new information in a 1080p signal from movie based content.

• The only time you would see a difference is if you have native 1080p/60 content, which at this point would only come from a PC and maybe the PS3. 1080p/60 does have more information than 1080i/30, but unless you're a gamer you will probably never see native 1080p/60 content. It is incredibly unlikely that they will ever broadcast 1080p (too much bandwidth) or that 1080p/60 content will show up on discs (too much storage space and no one is using it to record/film).
