That will change with time, though. Several movie studios have announced plans for 3-D Blu-ray releases, such as Coraline, later this year and early next year. And, always eager for more viewers, the TV networks have more 3-D channels and events like college basketball tournaments in the works for next year. To accommodate that new content, many TVs coming out soon, such as the Sony HX800, will be "3-D Ready": They will display three-dimensional images, but you can buy the glasses separately later. So if you're in the market for a new TV anyway, buying one of those models is a good way to future-proof your living room.
