I'm going to go out on a limb here and say Natal will flop. It does bring something new to the table. Just nothing anybody wants. At least not hard core gamers, which is the 360's core market. If Microsoft wants to tap into the fitness game craze, fine, Natal does the job perfectly, but if anyone can point any game genre that is going to be improved thanks to this new control device, please tell me, because I can't think of any.
Full body motion controls, as Nintendo knows well, are perfect for physical workout, but nothing else. You are going to be tired after 30 minutes of gameplay. That's exactly the point. 30 minute hard-core game sessions anyone?
These Goldman Sachs people are very, very wrong.
