I disagree. I think MGM has a plethora of genre titles that are deserving of a blu-ray release.
One example:
New Years Evil. Sim-shotdow by Jeff on part 2 of the Choice Cuts STYD video last week.

sadly
Food of the Gods,
Dolls,
Squirm,
Deranged,
Phantom of the Opera,
Scarecrows,
The Little Girl Who Lives Down the Lane,
To All A Goodnight,
Candyman 2,
Audrey Rose,
VINCENT PRICE MOVIES!!! etc etc etc. And I do mean ETC! There are so many more!!!
