A revamped "Cavalcade Of MGM Shorts" series of collections; perhaps splitting out the Pete Smith Specialties onto their own box set, as well as some of the other long running series in their own collections.
This is a bit of a long shot, but I'd like to see 2 moderately priced sets of the 11 Henry Aldrich films. This could be no-frills, as long as the print quality is equal to that of Universal's Ma & Pa Kettle and Abbott & Costello sets.
