I don't know why this is surprising. He's right. This is mainstream event. Thus you show off your mainstream titles. Both Sony and MS are doing the same thing. I mean MS spent 40-50 mins this year of their conference showing off nothing but casual things. Sony spent at least 30 mins doing the same.
Due to this even getting so much press, its best to show off what the mainstream will want to hear. And right now that's things like Wii Music and Wii Sports Resort. Doesn't mean they still couldn't show off mainstream core games like AC and what not but it's just the nature of the event.
Now I don't understand why they could show off more of their mainstream brands such as Zelda and Mario and whatnot but maybe they simply weren't ready to show off. I mean they aren't like Sony and MS that if they aren't ready they'll just make some cheap CGI video and say yea be hyped for something that isn't real yet. But once again mainstream events will show off what they believe will tap into the mainstream, and that's the Wii series which is why it got attention.
