If you have already played through to level 60 and collected appropriately powerful weapons, the main story in Psycho Krieg and the Fantastic Fustercluck will add 3-4 hours to the gameplay (more, if like me, you spend a heap of time switching between new weapons). However, if you jump in a little earlier on the levelling, I expect that this could take somewhat longer, particularly if you want to complete all the available side quests.
