The comments about the bland environments seem pretty funny,
1. If you like the RPG aspect of a game more then the graphic aspect-For example the environmental graphics in Fallout were really bland even though they represented the scene well. But after playing that game for twenty hours you are so used to it that those graphics became just really ordinary. However, if you like RPGs, you can still play that game now and consider it to be one of the best.
2. The first time you played Oblivion when it was brand new on a top of the line PC, one thought the dungeon/cave, elvish architectural, and oblivion plane graphics were really excellent and outstanding. Then after playing it for 30-40-50 etc. hours they do not seem as incredible nor innovative anymore. Any game you play for 30 or more hours, the graphics will become ordinary eventually and not impress you as much, you get realy used to them, if not slightly tired of them-this is true for almost every game.
3. If you want to trully see innovative art design -play Hex (Chamber of the Sci Mutant Priesstess) or Albion. That stands up better then any modern game graphic in innovation.
Worrying about how "alien", "innovative", "unique" the evironments look should not affect you're enjoyment of this game after a few hours. You are playing this game for much more then the best graphics. It is still an action RPG, and if it is the quality of the KOTOR series it is still more interesting in its RPG aspects then the majority of old school hardcore classics-many of which were dungeon crawlers, with lots of stats and good turn based combat-but thats it. And that includes classics such as the SSI gold box series, Might and Magic, Wizardry, and even BG 1, though most likely not 2. This game looks to have a good-to-really good story, and some good dialogue at least. Add to that at least pretty good combat, and free from exploration- you've at least equalled if not bettered KOTOR.
Plus, it is in a new IP setting, and at least not in the same hackneyed medeival fantasy world.
We shall see how good the game is, just think about this, how many CRPGs are even made in a setting other then medeival fantasy as a ratio, 1 to 9? Hopefully we'll see more genres represented in the market especially if it does really well.
