FCS2 - FCS1 = how much actual space taken up?

[Elmer_Lang]

Having installed everything I wanted from the previous suite, and will install the same ones this time too, and since all previous apps are to be erased, including gigs and gigs of STPro (Loops, et al), GarageBand and DVDSP, I expect the actual increase in space used won't be that much.

Does anyone have any idea how much more space will be needed in total? (I did not and will not install Motion this time either.)

best,
