I haven't seen much of the Wand while we've seen some early footage of Natal and the bashing it got on sites such as this one. Maybe that is why Sony isn't showing it yet, without a good game build for it to show what it can do then people are going to find faults in it. If they can show the Wand with a game build for it at the E3 then the hype is going to compleetly overshadow Natal. Not to say that Natal is doomed to fail or not as good as the Wand (nobody can judge that at this point).
