Yesterday, Nintendo announced that a new version of its hand held console will display 3-D games without requiring users to wear special glasses.

Many TV manufacturers are coming out with 3-D TVs (and 3-D glasses) this year, and desktop gaming is likely to be a major focus for 3-D consumer products. Nintendo is trying to get ahead of the pack by offering glasses-free technology, but how realistic it will look, especially in different lighting, remains to be seen. There have been glasses-free 3-D demos in the past, but these tend to be far less vivid than glasses-enabled 3-D.

The console will be available within the year and will first be demoed at the Electronic Entertainment Expo in June, according to the company, which did not provide details on how the technology will work.

Sony has said that 3-D games will be available for its PS3 before long, although these will likely require active-shutter 3-D glasses.

A Google-Intel-Sony partnership will soon offer TVs and set-top boxes that make it easier to browse the Web on a TV, according to a report by The New York Times. The Google TV platform will be based on the Android operating system and will be open to developers, who will presumably be able to create downloadable TV apps, like games.

While some TVs and boxes already allow Web access, these generally don't offer full web surfing. Products that let you play video from a computer on a TV have also been around for a while. But the rising popularity of video sites like YouTube and Hulu.com may mean we'll be seeing more Internet options--potentially even related social networking services--on TVs. Logitech will offer a remote control with a tiny keyboard to aid in web surfing on Google TV.

Google's venture into TV was preceded by its Google TV Ads system, which sells ads on some televisions systems and figures out where an advertiser's ad should be placed based on keywords (similar to its web advertising). Several years ago, Google also tested a software which used a computer's built-in microphone to listen and identify audio from a user's TV to target related ads on the user's computer.

Yesterday, Panasonic sold its first 3-D HDTVs at Best Buy in New York. For about $3,000, you can get a 50-inch 3-D plasma TV, a 3-D Blu-ray player and one pair of 3-D glasses (additional ones are available for about $150). Just the day before, Samsung announced that it will be selling three versions of 3-D TVs within the month and Sony stated that it will roll out 3-D TVs this June in Japan.

Samsung's sets will range from $1,699 to $6,999 and it will offer more versions in the spring and summer (some versions are already offered in South Korea). To coincide with the release of its first 3DTVs, Sony plans to release 3-D gaming software, most likely for its Playstation 3 system.

3-D Home Theaters have been available from Mitsubishi since 2007, at prices ranging between $1,500 and $4,200. Mitsubishi has also recently demoed a Nvidia driver that converts PC games in 3-D on its screens.

With so many 3-D TVs on the way, viewers will need something to watch. Satellite TV service DirecTV confirmed that it will offer three 3-D channels in June, while sports network ESPN plans to broadcast the soccer World Cup in June on its new 3-D channel.

The research firm DisplaySearch predicts that 3-D TVs will grow from the 0.2 million units sold in 2009, to over 1.2 million units this year, to 64 million units by 2018, with revenues forecast to reach $22 billion dollars by then. Currently, 3-D TV sets require viewers to wear 3-D glasses, but at some point in the future, consumers may be able to watch 3-D TV glasses-free.
