I'll have to get my pics off Facebook and onto Flickr, but there was a really nice Cammy walking around on Day 2, a really good Harley Quinn (original outfit) on day 3, and some nice booth babes (Bayonetta and two models for random fantasy game just outside the show room.)
I would highly recommend the Kotaku Cosplay articles from last weekend, they did a good job on finding everybody.
Edit: The winners in the linked article in the OP are the fantasy game models I was referring to.
