I am relatively new to Home Theater, and thus have a question. How often, or if ever, are new products released? Is it more like the computer industry with new releases every couple of months, or more like the car industry, with releases more around every year? Also, when are the new TV's released? Like Spring for yearly and winter summer for multiple relseases? Reason I ask is, I am going to get a new TV soon, and want to know if I should wait so the new models come out. That way I would either buy the one I want for a lower price, or buy the new model. Thanks. -edit- The TV's I am looking at are: Samsung 50" DLP Samsung 46" DLP From what I have learned, the only differences are aesthetical and price. Am I wrong? Which would you prefer?
