This isn’t news, we’ve known this for months. There were articles 4 months ago with the devs talking about how these 2 games didn’t meet sales expectations. At least one of them is out on PC now, though I haven’t played yet because it’s only been a day and the download is 140gb.
Space Marine 2. It might happen, or it might not. The devs think it could be a good idea but Sony isn’t currently interested and it’s not being worked on. This is like the courier in Skyrim running up to tell you you’ve got no mail.
