With mass production of 1080P chips from various manufacture’s including Texas Instrument's DLP shipping in large numbers, the buzz seems to be in full swing in the HT community. 

On the thread linked to above I play devil's advocate, pointing up the need for level headedness and not to getting carried away with the euphoria of a 1080P revolution.  We still have a long way to go before existing HD resolutions are considered a mature technology.  But those excited by the new standard are willing to take whatever “improvements” they can get.  What kind of improvements can you expect if you spend the extra money it would cost today on a 1080P display?  None for DVD, some say that 1080i de-interlaced will present a better picture, but since I haven't seen it yet I'll reserve my judgment.  Personally I don't see how except, possibly when images are in motion you might get tiny, near invisible improvements from the de-interlacing.  1080i is produced from the same bandwidth as 720P, the two HD video resolutions are effectively the same thing, CRTs happen to natively present 1080i and fixed pixel display technologies present 720P.  Now the same amount of video data is used to fill a digital display capable of 2X the bandwidth of conventional HD, are there improvements?  This reminds me of the late 80s when they started building TVs with more scan lines than the NTSC broadcast was capable of.  More rows of phosphor dots in the face of the picture tube was supposed to give a better picture to the standard NTSC broadcast.  Eventually the "feature" became a common practice but it’s still the same old NTSC image.

Choice exerpts from a discussion on the HT forums:

“To me, the question isn't so much as when will we get 1080p sources, but simply 1080p (with proper upscaling) at the display.

For example, we all know and love (to some degree ) DVD. DVD is 480p. But it's encoded on the disc as 480i. So to me, the importance of a 1080p *display*, is to be able to deinterlace 1080i sources up to 1080p.”  Kevin Brown HTForums

“1080i gives you 60 x 1920 x 540 pixels per second.

1080p gives you 60 x 1920 x 1080 pixels per second.

Double data rate but resolution is still the same. You get 30 times full 1920 x 1080 images from 1080i but 60 full 1920 x 1080 images from 1080p.”  Sammi Kallio HTForums 

“I just can't help my skepticism. You may see an exciting new video format but I see potential fragmentation of the market, confusion of the true definition of HD. More fickleness at adopting additional expenses of HD recording, broadcast and transmission equipment.

At best, 1080P is simply ignored by the industry. At worst it delays the DTVization of North America.

My biggest fear is that buzz around 1080P might cause one studio for one network to delay buying that one digital HD camera in anticipation of yet another standard. Does 1080P today mean 2160i tomorrow?

I want to see the breakthroughs in market adoption and consumer acceptance. I want to hear that Digital TVs outnumber SDTVs in America's livingrooms. I want to hear about HDTV TV commercials (a barometer of the health of the DTV revolution). I'm bored with technological breakthroughs already. “  WaydeR HTForums
