[QUOTE="mjarantilla"]The Xbox has more advanced shaders than the Wii, that's what makes games look better. But the Wii is capable of larger scale and more detail in terms of stuff like textures and pixels.

That's not true at all... Even the TEV unit in the GameCube is capable of all of the same shaders as the XBox... The problem with the TEV is that it is more difficult because of the extra stages that need to be implemented to achieve the same results... The shader has to be re-writen for the TEV or emulated...
Most 3rd party GameCube games were ported PS2 source engines that the GameCube ran in it's sleep because they were done using only vector units. Very few games were developed from the ground up on the GameCube. Example of games actually using the TEV are, RE4, Rogue Squadron 2, Rebel Strike, SMS, Metroid Prime 1, Metroid Prime 2. All these games mentioned have very advanced shader effects including (not all), ray tracing, bump mapping, environment mapping, real time light sourcing, real time self shadowing, light blooms, light scattering (Rebel Strike, only TEV can run this shader which is every bit as good as HDR), dirt mapping, AA, etc.
Now take the Wii's TEV which has 16 hardware stages as opposed to just 8, double it's pixel pipes from 4 to 8 and add an additional 64megs of ram and you get the idea of what in can do... Something that people seem to forget is also that the GameCube had a total of just 3megs of ram with S3TC texture compression for graphics. The Wii has a total of 67megs of ram (3 embedded and 64megs off die) for graphics.
Factor 5's Julian Eggebert also said that their engine for the Wii can do every single shadder effect that the PS3 can do... Can the Wii run the same quality graphics as the Xbox? Oh yeah and beyond. Mario Galaxy did it and it was a GameCube ported engine.
Finally, someone that know something about programmable gpus.
