Hmm, Uncharted 3 aside I'm struggling to think of any games this year with memorable soundtracks. Deus Ex had a vague electronic feel to it if I remember correctly and I couldn't give you a single note from Gears 3. In fact I've been playing Battlefield 3 and I couldn't even tell you if there's a score or not!
I'm really looking forward to Skyrim from an aural perspective, in Oblivion even the music as you just wandered around the forests was spot on, or the way it got more ominous as day turned to night. Plus the title music still sends shivers down my spine, even after 5 years.
I imagine that Zelda will have a pretty awesome score as Nintendo are generally great at scoring their own games.
