LOL! Why?! They already are selling 4K sets. Why would they research what they already know? It's not like they're deciding whether to sell 4K or not. They want to get the word out!
THIS IS MARKETING. Back to my original point, Best Buy is doing this to make money. Simple as that. NTEK gets to go along for the ride.
NINJA EDIT: Best Buy has little effect(if any) on what TV manufacturers are going to be offering, and they are the driving force behind 4K.
