Eh, not so fast:

Sharp's proprietary quad pixel technology adds a fourth color, yellow, to the traditional RGB pixel format, enabling many colors to be displayed for the first time. Featuring more colors than any other television, see never-before-seen colors like sparkling golds, Caribbean blues and sunflower yellows. On the LC-70LE735U, this technology is enhanced further with Quad Pixel Plus, which produces smoother lines by enabling the individual control of all 8-million sub-pixels on the screen. The proprietary AQUOS 3D LED system comprised of the X-Gen LCD panel and UltraBrilliant LED backlight enables an incredible dynamic contrast ratio of 6,000,000:1 for excellent picture quality. AquoMotion 240 virtually eliminates blur and motion artifacts in fast-moving video. The LC-70LE735U features Smart TV, including the addition of Vudu apps, Netflix streaming video1, CinemaNow capability, along with the industry's leading online support system, AQUOS Advantagesm Live. And, with built-in WiFi, connectivity is easier than ever. Dual USB media players for portable video/music player are also included for your convenience.
Then again, I'm not sure if Sharp is passive or active with their approach to 3D TVs. I'm pretty sure that this one could be something to see. Then again, you got this model:
Sharp Aquos LC-70LE745U 70-inch 3D and Wifi LED TV
There's a reason why Sharp's one of the better known flat-panel television names around for larger sized TVs.
Now I know that there are some Sharp Elite models in the 70" range, too, but not sure what type of budget you're looking at, but the Elites are far better...especially since they are full array locally-dimmed LEDs.
Like I said, not sure if Sharp's in the passive 3D market, but for the moment, they are one of the only brands with 70"+ 3D TVs in general that I can think of.
