proably a name brand, flat pannel LCDs were going for $5000 about 5 years ago and now the average price is $1200-2000 depending on the brand. the price will continue to drop as manufacturing cost come down. Companies want their product to go to as many people as possible. if they can offer the same product and they invent a cheaper more efficent way to produce that product the price is going to come down and competition will also help force down the cost as well.
For instance look at the ps2, when it first came out it had hundreds of moving parts and eventually they were able to make a ps2 slim with under 100 working parts. how long did it take for them to make that unit and with intigrated network capabilities, and a progressive scan DVD built in. the orignal ps2 did not have those options.
