Fewer Zelda-style games on the market compared to action games, especially with Bayonetta coming out at the same time.
Then you have Dantes which is straight up GOW like.
Then Darksiders thats like a mixture of em all but with Zelda.
Don't get me wrong, I'm excited about Darksiders very much. Though I still highly awaiting Bayonetta and Dante's as well. Then again I played all three at Comic-con in July and decided then and there I was going to pick up all of them when released.
