I could be tempted to go multi-region for some of these titles, especially The Fog and The Burning, never seen Night of the Comet, Lifeforce I thought was ok when I saw it many years ago on VHS, The Howling only if it has decent extras(always preferred AAWIL personally) and Day of the Dead really has to be something special because I'm more than happy with my copies from "that English company who aren't as good as the God-like SF"
Overall, I think it's a pretty good announcement for SF fans and with the announcement of The Burning, maybe we might get a BD of it over here in the near future
