Sharp has not revealed their 2011 TV line-up yet but we have managed to get some information from a reliable source about a coming flagship X5 range. The X5 range will feature Full LED backlight with local dimming in 60 and 70 inches.
Update: The Elite X5 models have now been unveiled:

Sharp has unveiled a LE830 range and the 70-inch LE73x range. According to our sources they also have the X5 flagship model prepared for August 2011 – before IFA 2011 in Berlin. We have no pictures of the TV at this point but our sources say that it’s going to be slim and “very elegant”.

Sharp X5 will launch in 60 and 70 inches called LC-60X5 and LC-70X5. It’s the successor to the previous XS1 that was launched a few years ago.

Sharp X5 will feature backlit LED with local dimming, scanning backlights, 200/240 Hz, Quattron, and 3D. A range of multimedia functionality have also been incorporated such as the Aquos Net+ internet platform, Skype, DLNA, Wi-Fi and USB playback with DivX HD support.

We have also received information that X5 will include a built-in hard drive, dual tuners and iPhone/iPad remote controlling but we cannot confirm that information at this point.

Sharp X5 is scheduled for august 2011 release in 60 and 70 inches. The price is said to be much more “reasonable” than the previous XS1.
