The new Dio deluxes of the first three albums are quite good. Some live stuff I didn't have. There seems very little unreleased studio material about though.
from a number of interviews, both concerning sabbath/dio, and initally, Heaven and Hell, I get the impression that Ronnie wrote what he needed to write and shaped the songs into what he wanted. in other words - if the album needed 10 tracks, he wrote 10 and that was it.
I doubt there's alot of unused stuff around, certainly from the later years.
the new deluxe version are very good indeed - I like them alot
