I own both the XBox 360 and the Wii, and I still think that Project Natal is doomed to be their next "Zune" or (worse yet) the next Microsoft Bob ...
Back in the day, long before E3 2006, I knew that the Wii was going to be a success because when I showed off the trailer to my diverse group of friends there was instant interest from (pretty much) everyone. Over the past little while, I have shown off the Project Natal video to several people and it (certainly) hasn't been nearly as positive as the Wii reactions were. There were positive comments, but most seemed mixed ... One comment stood out and it was (essentially) "That looks cool I hope Nintendo copies in in their next console"
The most drastic difference in reaction between the two timeframes was that there was almost no questions showing interest in buying project Natal. Questions like "When is it comming out?", "How much will it cost?", and "Will it be bundled with the system?" show that a person is starting to consider buying it; and these kinds of questions were absent from people when I showed the Natal video.
This is just my experience, and it certainly doesn't mean that Project Natal has flopped, but I would suggest that people should me much more realistic about sales expectations for it until we know more about it.
