In case anyone else was curious of the difference between the new Sharp 82U and 92U series, I have compiled a list of the major feature similiarities and differences directly quoted from the Sharp USA site, and have made the comparisons below.
Based upon the MSRP's you can expect a 13.5% premium ($500) to upgrade from the 46" 82U to the 92U, and a 10.4% premium ($500) to upgrade from the 52" 82U to the 92U. You'll have to decide for yourself if the increased NTSC color coverage, 5000:1 increase in contrast ratio, and addition of a DVI-I and RS232 port is worth the increase in price.
Here's the quotes from Sharp's press release pages on the D92 Series:
"The D92 series... features.. true 16:9 1080p (1920 x 1080 resolution)..... produced at the company's state-of-the-art, 8th generation LCD plant in Kameyama, Japan.... the D92 series... provides an unsurpassed Dynamic Contrast Ratio of 15,000:1... and 120Hz frame rate conversion, double the traditional 60Hz driving speed... pixel response time is an industry-best 4ms... All three models in the D92 series and the LC-65D93U incorporate Sharp's proprietary 5-wavelength backlight system... The D92 series TVs and the LC-65D93U incorporate ATSC, QAM and NTSC tuners... The LC-42D92U will be available in April for a Manufacturer's Suggested Retail Price (MSRP) of $3,99.99.
The LC-46D92U will be available in January for an MSRP of $4,199.99.
The LC-52D92U will be available in January for an MSRP of $5,299.99.
The LC-65D93U will be available in March for an MSRP of $10.999.99. "
Here's the quotes from Sharp's press release pages on the D82U Series:
"new Kameyama No. 2 generation 8 LCD factory with the debut of the AQUOS D82U series... with built-in ATSC, QAM and NTSC tuners... The D82 series also features full-spec 1080p (1920 x 1080) HDTV resolution... an impressive Dynamic Contrast Ratio of 10000:1...

LC-46D82U will be available in February for an MSRP of $3,699.99."
Both the 82U and the 92U Series feature
120hz frame rate conversion (which we believe = Micronas TruHD chip)
4ms response time
ATSC, QAM, and NTSC tuners
Are manufactured at the new Kameyama II plant
3 HDMI and 2 Component inputs all capable of accepting 1080p signals as an input
Features that differentiate the two series:
82U includes a 4-wavelength Backlight Display Unit; 92U includes the new 5-wavelength backlight system (Supposedly better color reproduction, I'd love to see numbers on the % of NTSC coverage for both models)
82U has a 10,000:1 contrast ratio, 92U has a 15,000:1 contrast ratio (I'd also LOVE to see a side-by-side comparison and reviews on how much of a difference this makes, and I'd love to see the ACTUAL contrast ratio numbers between the two series.)
The 92U series adds DVI-I and RS232 ports
The 46 82U's MSRP is $500 cheaper than the 46 92U's MSRP (13.5% premium) The 52 82U's MSRP is $500 cheaper than the 52 92U's MSRP (10.4% premium)
