3-D television expected to come to homes in 2010

And, although television makers haven't released specifics, the price of 3-D TV -- which requires a new television, broadcasting content and 3-D glasses -- is not expected to be substantially higher than some high-definition televisions on the market now.

These next-generation televisions would be able to play shows in 2-D or 3-D. They also would be able to show video games in 3-D, which Sony demonstrated at the expo in Atlanta.
