Bioshock 1 DLC and Museum ~1GB
Bioshock 2 Full Game Install ~9GB
Bioshock 2 Patches and Game Utility ~4.5GB
Bioshock 2 DLC (All 5) ~4GB

Now you probably wont have both installed at the same time, but it's still an insane amount of space if you did. For anyone looking to pick this up to replace your copies of Bioshock 1+2, you might want to hold onto at least BS2, and save yourself a ton of space.
