Their site does tend to be a bit out of date.
I find the best way to find out about any future releases is to look at sites like HMV or Play.
Speaking of future releases they have an anniversary edition of
Total Recall up for release in June, as well as
Cannibal Apocalypse with John Saxon...
They also seem to be re-releasing some of the old Momentum World Cinema releases (
Le Mepris,
Delicatessen etc.).
