We already had a pretty close idea about Sony's planned lineup of Google TV products after last week's leak, but today they've made it official with the launch of four HDTVs loaded with the web-enabled interface. The lineup will be sold through sonystyle.com and at retailers such as Best Buy, carrying the Sony Internet TV moniker, and include 24-, 32-, 40-, and 46-inch models ranging in price from $600 to $1,400.

The smaller unit uses a regular CCFL backlit LCD while the larger sizes sport Edge LED backlight technology. Other than that, all four models feature 1080p resolutions, an Intel Atom processor, 4 HDMI and 4 USB 2.0 ports, and Wi-Fi connectivity. Sony's TVs will come preloaded with several Google TV apps including CNBC, NBA, Netflix, Pandora Internet radio, Twitter, YouTube and Sony's Qriocity premium video streaming service. Users can also browse the web using Chrome, and starting in early 2011, access a myriad of other apps through the Android Market.

For those who don't want to buy a new HDTV, Sony is also offering a Google TV Blu-Ray player priced at $400, giving customers one more way to integrate the web with their TV viewing experience. All of Sony's Google TV products include a remote control with a thumb-sized QWERTY keyboard, making it simple to search your favorite TV shows or websites.

This marks the second major release for Google TV devices after Logitech unveiled the $300 Revue set-top box in early October. But the search giant is not alone in the quest to dominate the living room screen. In fact, its rivals seem to be pushing much more affordable options, including the $200 Boxee Box, the $100 Apple TV and the Roku box, which starts at $60. Whether consumers will pony up the extra cash for Google TV devices remains to be seen.
