If you didn't already know, The Witcher 2 Enhanced Edition will make its way to Xbox 360 on two discs on April 17. If you are planning to get The Witcher 2 on Xbox360, make sure you have 15.4 GB of free space on your HDD to install the entire game. It's highly recommended to install the game on your HDD for the best performance, The Witcher 2 Level Artist Marek Ziemak has told Eurogamer in March 2012: 

 "That's a thing we want to stress, that if it's possible to install the game [then do so], because the streams will be faster, you'll experience some better visual quality, because the hard drive is much faster than any media," 

"It will improve loading times, it will improve the quality of the meshes, probably also because we have faster streaming means faster movement between memory and hard drives, so you'd be able to load the good chunks and then just change them directly from your hard drive."
