Really interested in this, it is Silent Hill after all but it hasn't been publicised a huge amount so I'm a bit unsure about it. I'll probably pick it up somewhere down the line because I enjoyed Homecoming and I don't imagine this'll be too different.

this has got my interest as well you looking forward to the HD collection?
