True, but Sony and Microsoft have FILM quality graphics. Sony has very good cinema scenes, mainly from their movies they've had like Spider-man and such.
The XBOX hardware is mainly running off of the NVIDIA graphics card. What do expect Microsoft to do there? They've stripped apart a computer and put it in game-format. There system is good, but they have NEVER put time into creating it to have unique qualities and such.
GCN has all of that. The main processor of the GCN has more elements to create on the screen (fog, lighting, etc.) and can surpass anything that XBOX would throw at them. What about Sony? Did you not forget that when Nintendo wanted to make a system (which led to the N64) that utilizes CDs for the games, that they called upon the help of Sony to do that?
Sony took Nintendo's ideas and came out with the PlayStation. And the N64 still kicks the PSOnes butt graphic-wise.
The GCN will live on far enough, even if Nintendo makes another next-gen console, they still won't quit making the GCN, because NO othere developer has ever pumped out the the GCN's full capabilities at all!!
