Warning this is one of those "pointless" threads.
I was in large corporate chain retail store with employees in blue vests yesterday and passed through the game section to see what they were charging for the zapper. There was a couple looking at the Wii section, and they looked kinda confused so I asked them if they were looking to get one. So I got started into a nearly 10 minute conversation about the Wii compared to 360. I gave a pretty good sales pitch, but just like most casual consumers out for a Wii now, they seemed to be leaning towards a 360 for their youngsters mainly because they wouldn't have to search high and low for a Wii.
It's a shame for Nintendo's sake that they still are having trouble meeting demand.
