Why even bother dropping the price, when Sony is selling more PS2s than Game Cubes and XBox's put together? It's simple economics. Once the other two systems start gaining ground, that's when you'll see the price start to drop.
Also, consoles such as the XBox are sold under cost, the hope being that they'll make the money back on the games (their own sales, as well as development royalties) and accessories. I'm not familiar with the actual cost of a PS2, but if it's similar to the XBox scenerio, there's probably not much more room for them to drop, w/o losing money.
