I was talking to my next door neighbor about the Wii, and he told me about a friend of his who played it around another friends house with his wife and they really loved it, they had talked about it for a quite a while - and they are all in their 40's. (that is my neighbor, his friend and his friends friend, but not his friend's wife, who is a bit younger...thats clear right? :) )
Well simply put, Interest is still very high here.
