I just read through this article over at MMORPG.com and this article at WinterBlink.com about the Ambulation info revealed at Fan Fest 2007. The article mentions the complexity that will come with the facial customizations, adding wrinkles and other deco to the character faces, it's all pretty amazing, also the fact that you'll be able to set your characters mood, or emotional state, and that will affect all of the emotes that you activate, if you set your mood to "sad" and then you wave, your wave will look sad... very interesting and innovative features for the role-player in all of us.
It sounds like there will only be shirt/pants combinations for clothing, but at the same time, they have a professional costume designer on staff now, so I get the feeling that to compensate for the lack of diversity in types of clothing, there will be a plethora of styles and many color options. Another benefit will be the seamlessness of clothing, the fact that it will all go together well. I still haven't heard an official word on wearing decorative weapons, but I certainly hope that becomes an option at launch, just one more thing to add to the "gritty" feel of EVE.
