I would NOT believe a word about Stalker until it's out. I've been through this with FABLE already. What's the background of this developer? What games they released in the past? I guess none of us will be able to answer this. My opinion is that a new studio or a studio with little experience in making more basic and less ambitious games has very small chances of developing something huge like Stalker and keeping all the promises.
