I think that some of you are missing the point of my question.
In classical music, there are collectors as fanatical as in jazz. The RCA Shaded Dogs, the Mercury Living Presence, The DG Originals, the classic EMI recordings of the 60's and 70's and the classic Decca recordings are as fiercely coveted as the RVG's among jazz collectors. Yet, in each of these mid-priced editions, the respective record companies (EMI included) have chosen to have these discs include enough material to come out at 60-70 minutes on average. The point is why can't EMI do the same thing with the RVG's?
