>We should celebrate their fall, maybe there will be room for some real competition.

How are you going to get more competition when the entry cost is so high? The only competition will be the Chinese willing to dump endless cash into this but they are not doing it out of the goodness of their hearts either and it will still take years. If NVIDIA starts to falter then in the short term things will get even more painful for consumers as AMD becomes the new crummy company people love to hate.
