I downloaded the CGI trailers. I looked at video comparisons on youtube (you wouldn't believe the fuss made about which version looked better--PC/360/PS3). I read the reviews.
I bought Dragon Age origins for the 360 yesterday. You would not believe the look of disgust that was on my face when I saw this game running on my HDTV! Holy shit, is this game ugly!! I'm sure it's a great game and I intend to really get into it today but, at this point, I think any version of this game is going to look like ass.
