Samsung and Sony are looking out for themselves and their dealers. Samsung is already the Apple of the display market and most people are probably willing to pay a premium for their products. Sure, there will probably still be sales, but only ones that are vendor-mandated that make the price the same whether you buy at Sears, Best Buy, Amazon, etc.
Retailers may be able to differentiate themselves like they do for existing price-protected products by offering free gift card with purchase of an ES8000 or something.
As someone who sells TVs for a living, I can honestly sort of appreciate this move. It gets tiring when people come in, pick my brain about a TV, mess with our display unit, and then ask me to match an outrageous internet price that is near or below cost. A TV is like anything else you buy - a dealer who sells it with razor-thin margins can't stay afloat.
Looking through BB employee news there is mention of PNXXE8000 sets coming in mid-March, and reminds employees that due to new pricing policies from Samsung, price overriding and discounting of any of these sets is NOT allowed.
