One thing I'm not clear on is how much of this is cause and how much effect: that is, does NVidia cheerleading for something make it more popular with the tech press and then everyone else too? There are definitely large parts of the tech press that serve more as stenographers than as skeptical reporters, and so I'm not sure how much is NVidia picking the right next big thing and how much is NVidia announcing the next big thing to the rest of us?
