The
listing at ShopTCM shows that this will be part of the
TCM Vault Collection.
IF "1930s Rarities" is marketed like other
TCM/Universal sets, the following
may apply...
- They are exclusive to TCM's online store and its distribution partner MoviesUnlimited. General retail at a later date (i.e., ~1 year), but not all TCM Vault titles receive that wider availability.
- The initial production run is pressed DVDs. Once those are sold, orders are transitioned to DVD-r MOD production.
(At this writing, there also appears to be release date confusion... TCM says August 6; MoviesUnlimited says September 6.)
