Dragon Age - Golems of Amgarrak DLC Preview

This is the first time I've seen the name of the new "combat oriented" DLC for Dragon Age, with Joystiq previewing Golems of Amgarrak from Comic-Con.  The author describes his short gameplay experience but doesn't really reveal much:

So yes, alongside the public, I got a chance to see the upcoming DLC. And the first thing I heard about it is that it's hard. Really hard. Dragon Age: Origins  is already a game that requires some thinking, but BioWare has apparently turned up the difficulty on this one -- there's lots of big enemies, I was told, that will provide a challenge even on the easiest setting.
