SomeDude was saying that console games are far more stable. Which has nothing to do with content.
Not entirely true. The more content you have, the more content you have to generate and QA. Content generation is very time intensive ($$$), and so is QA... especially on the PC platform.
If you try and force a console-level quality on PC games, then you either have to spend a lot more money on it, or you cut the amount of content to stay in budget. And since cutting the content reduces costs in two (or more) places... guess what'll happen?
That said, the claim that console games are perfect is bogus; numerous (maybe even most) games have "glitches", some of which are game killing. And I bet you'll see the quality of games go really south on the PS3 (and, to a lesser extent, the 360) now that hard drives, and thus patching, is available.
