Uhm... Excuse me? Load times too long?
The Xbox is more or less consistently the fastest loading of the three current consoles. The GameCube has a theoretical advantage because of the way the discs are structured, but in real life terms that is often beaten by the combination of the harddrive buffering on the Xbox.
Go look at some of the comparative reviews on IGN.com. They do cross-platform reviews and one of the things they look at is how fast a game loads. A couple of times the PS2 has done well enough, but (to throw in a random number) 9 out of 10 times the GameCube and Xbox will beat it.
