One such list on their fine site is the Chopping List (Also linked in our sidebar). The frequently updated list has a rundown of all the upcoming releases on home video, and notes if their DVD, Blu-ray, Remake, Special edition, etc.
This list is a great resource for those wondering what's on its way out next. Though it only covers the horror spectrum of releases, it does that aspect better than any website you can find. I check it frequently just to keep myself up to date... it's great to find out "that movie's coming out next week?! Awesome!" Bookmark it, and check out their magazine when you get a chance... both are top notch!
