VG247 put up an Interview with senior producer Tomek Gop. Let's jump right to the significant part:

<p style="margin-left:50px;border-style:solid;border-width:1px;border-top-color:#ffffff;padding:5px;border-right-color:#bbbbbb;border-left-color:#ffffff;border-bottom-color:#bbbbbb;">What made you decide to give Geralt a ponytail this time around?

Tomek Gop: We’ve redesigned a lot of Geralt’s attributes. His clothes, some of his weapons, and so on. The ponytail was one of the things that fit the overall view this time. It’s not like we did it on purpose. Besides, fighting monsters might be wiser with your hair fastened – just in case you needed a more gameplay-related explanation.

Geralt is pretty much the Captain Kirk of the medieval world. Will he have just as many female conquests this time around or will he decide to settle down with one gal?

Tomek Gop: What Would Kirk Do? Geralt has always been sort of womanizer, so you might expect relations this time as well. It was important for us to rethink and redesign the presentational aspect of sex, nudity and romance in The Witcher 2. We focused on this being more bound to the story, and less “collectible”.

You could expect that this time sex means actually two people getting close to each other.

Geralt - the Captain Kirk of the medieval world.
