In my opinion, they are just saying that in order to improve sales. If people believe them, then they will not postpone purchases in the hopes of lower prices in the future. In other words, I do not believe LG, and suspect them of simply being liars who will say anything in order to make more money.
In fact, if betting were allowed here, I would be willing to bet that prices will continue to fall. And please, next year, someone revive this thread and either tell me that I was right, or point out that my prediction was wrong. I welcome it.
