When The Witcher 2 releases on the Xbox 360 next year, players can expect that the game will be on two discs, which is no surprise as the game is packed with lots of contents.
According to CD Pojekt, The Witcher 2 on the Xbox 360 will include all of the DLCs that came out on the PC version. This includes all side quests, fixes, and the upcoming 2.0 update that will release this September 29th. Considering the game is more than 8GB on the PC, two discs are expected.
There is still no confirmed date as to when the game will come out on consoles.
