It could lead to more in the future, but I'd think that TCM, owning a bucketload of MGM titles in addition to the Warner catalog, would only show the Monogram Chans (see the "Chanthology" DVD set, released by MGM - said Monograms being snapped up by Allied Artists who, in turn were ultimately snapped up by MGM, who, partially anyways in terms of catalog, was snapped up by Turner).

So, unless Turner (TCM) wants to tangle with Fox or they work out some sort of broadcast deal, I don't think we'll be seeing Warner Oland and Sidney Toler in his healthier days on TCM.
