Yes agreed there with LCD's, but it seems that they're talking mainly DLP's at the moment..
I'll have to give it another read and see if I've missed something..
That is because LCD's take a significant number to achieve usuable output and a as the number required becomes greater in value the technology is less and less an ideal situation. LCD projectors already exceeded the advantages and capabilities, and manufactors now begin to try and throw in new features to intice customers (don't get me wrong some are nice) but often at the expense of other things, then they improve specs not relevant to what technology is available to utilize these advancements that are not clear in advantage to previous models. DLP offers more potential for the future market and the industry is well aware of this.
