I caught up with the CD Projekt guys in Sydney earlier this month, and they seem to believe that, with The Witcher 2: Enhanced Edition, they've created one of the best looking games on the Xbox 360. This trailer seems to be a strong argument for that assertion.
This 'new elements' trailer, believe it or not, goes into some of the 'new elements' being added to the Xbox 360 version of the game, but unless you've actually played the original, it'll most likely be difficult to spot what's new and what's not.
I was impressed with manner in which CD Projekt has managed to port the game across to the 360, not just in terms of visual quality, but the control system and the menus. It all works quite seamlessly, and I fully intend to play The Witcher 2 on 360 when it's released.
