I guess it makes some sense in that lengths of albums originally released on vinyl in its heyday was typically 40-50 minutes or so. CDs offer 70 minutes. Newer releases straight to CD take that into account. Thats somewhere between 1.5 and 2 traditional 33 1/3 vinyl lps. So that math says 3 sides is right in teh ballpark.
For $30 a pop, a premium over CD, they could add some more useless bonus tracks in there though still. :^)
