You could try e-mailing them and asking for some info, though I have a feeling they won't tell you much. Other than that I don't know, as the October schedule isn't up yet.

We haven't yet released any sort of list. As soon as we do, however, you'll find out about it here! I'll keep you all posted.

How does everyone feel about having 31-Days of horror?
I myself think this is a terrific idea and incredibly possible.
Once October hits its pure Autumn/Halloween season, so why
not take full advantage and fun of this glorious month?
You can easily fill the calendar with 24/7 great classic horror with out
sequels or remakes. (Not that there is anything wrong with a good sequel or re-make?)
I can make a list off the top of my head of at least 100 great and I do mean great not cheesy horror movies to fill your October schedule.
If AMC is concerned of losing a fan base of regular viewers for this month I can assure you you will be wrong. Your horror fan base is huge, and keeps growing.
Have you ever heard of a Comedy or Drama fest? NO!
Why does Christmas get 31-Days and Halloween only 13 when Halloween is the 2nd biggest holiday?
Food for thought….

I just hope it's nothing like last year. El sucko supreme!
