I'm personally tired of ooh-aah choir in game/movie soundtracks. Not in the sense that I don't think they have a place, but they're used too much. Be it carmina burana-style choir to convey disaster/desperation or wavering ooh-aah choir to convey mystery, it should be saved for those moments so it retains its effect.
I'd like to talk a little about fantasy rpg-music in general. I, like a lot of people, loved NWN2. However, I feel that the music was a weakness of that game. Not the individual tracks mind you, but the overarching theme of doom and gloom. No matter where you are, be it a friendly town or city, or deep in a orc citadel the music conveys this sort of lingering depression. Once again, I'm not saying those sort of tracks don't have their place, but I hope Eternity goes for a bigger variety. There are so many more things to convey in a fantasy world than mystery and darkness. Adventure, revelry, bravery, zeal, insanity, various cultures and serenity. Given a musical queue, those all sound very different in my mind.
I'd also like to make a note about combat music. For a long time now there's been this idea of having an area theme and a combat variety of that theme. In NWN2/Oblivion/etc I feel like combat themes have a tendency to either not sound like combat themes or sound way too overdramatic for what is actually going on. Having the music go into doomsday mode because you stumbled over a starved rat only to cut out again instantly as it dies a second later does not good atmosphere make. I also feel like combat music doesn't have to be in minor. Not to make a direct comparison, but jrpgs often have the combat theme convey adventure rather than desperation. It's a game after all, and combat is one part of the fun!
If I were to offer up something I feel is worth taking inspiration from it's the heroes of might and magic-series, for example this battle theme:

Some field themes in major would also be nice. Surely the whole world isn't dark and mysterious, even if there's danger? Maybe I'll hurt my "cred" bringing it up, but I think FF12 had some great field themes (when I say field themes I just mean 'not in a city or dungeon') like this one

Obviously I'm not saying either style should be taken wholesale, but I feel like music in fantasy rpgs could do with a bit more variety.
edit: dang it, forgot to comment on the tracks themselves. The second and third track with the glockenspiel have a soothing sound, and I can't recall hearing anything similar in any games as of late (or even looking pretty far back). Very nice, gives me hope for the rest of the soundtrack!
Okay, I'm done! Sorry if this post ended up being a bit bulky.
