In this vein of news reaction, I was also listening to the local talk show (Woody, Tony, and Ravey) on the radio during my commute. A lot of the time they have a video game segment near the end of the show, and today was no exception.
During the program, someone phoned in with the details on the Wii launch (price and date) and later someone phoned in asking what that price was, and was then very estatic on the phone when they told him "$250 with Wii Sports". Unfortunately, those were the only two times the system was mentioned during the whole segment. :-S
I'm still floored at the amount of hype the PS3 is generating too, which seems to come mostly from casuals (considering the interest in Madden during most of these segments, I'd say this is a prime example of that market). Like someone else said, it's probably going to take them actually walking into the store and seeing the $600 price first hand before they finally go: "whoa... is it really worth that much to me?"
