LG is supposed to be releasing a 15" OLED TV sometime in the middle of this year. The estimated price is around $2,500.
Sometimes it is expensive to be an early adapter.
LG also announced they will be releasing a 30" OLED TV sometime in 2012. I don't really wanna know how much that will be if a 15" OLED TV is estimated to cost $2,500. The 30" will probably end up costing around $2,500 - $3,500 since it is coming out two years from which give time for both increased production facilities and also competition.
