Well, looks like price fixing is a recurrent habit amongst big companies [in France, the three major cellphone network companies have recently been fined a hefty 300 million for price fixing], and that LCD manufacturers don't want to be left behind. Japanese, US and Korean authorities have started investigations on Samsung, Sharp, NEC, LG Philips and some other LCD makers. They are thought to have had talks to artificially maintain high prices on their respective products, when competition should have driven the prices down.
In any case, it ill probably take years for anything to happen... So don't expect the price of LCD TVs and monitors to plummet anytime soon ;-)
