Up to and including PEGI 16 allows plenty of games. In a way this just makes it a bigger clusterfuck ... providing a force to downgrade rating levels for PC games. What does Microsoft care if they fracture PC gaming and make "mature" games a harder sell on it? They only see it as competition for the XBOX after all.
I'm not entirely sure how it fractures it. Metro app. games are an entirely different class than the traditional "core" PC game. Unless we're all thinking that Bethesda, EA, Activision, UBIsoft, etc. are all going to abandon AAA game developement and start focusing on the equivalent of Browser based games, I don't see how this is going to affect gaming in any way.
At the most we may see the more casual titles on Steam move to the Metro App. store. Hell, I don't even think an indi title such as Dungeon Defenders would be able to make it into the Metro App. store. Microsoft's own Age of Empires Online can't qualify for the Metro App. store, as far as I know.
Microsoft is deliberately making Metro Apps. (including games) small and quickly downloaded. The major demographic for Metro Apps. is likely to be WP8 and slates/tablets where devices will predominantly be downloading through 3g/4g/whatever cell phone based network is available. Hence, small and lightweight apps.
That's not going to do anything to fracture PC gaming unless you think PC gaming is only about lightweight casual/browser type games.
Anything above and beyond that is going to be completely unaffected and likely still sold through Steam, retail, or other online DD vendors.
