Future plans...

[Ca-Kal-Oh!]

This is actually a question for the creators of Penumbra, but any other comments are most welcome
I am interested what are the future plans(if any)for you guys, after you release Penumbra:Black Plague?
More precisely, Im a bit curious if you have abandoned UNBIRTH(I trully hope you haven't), or you are still having plans for it?
I know that Penumbra is a "successor" of Unbirth, but as you said the games have different story, ideas, etc. so I hope there is still place for it to come back to life again!
If you don't have such plans, please at least answer me if you are going to continue with the horror genre or not?
I have played countless horror games, but I think you have one of the greatest potentials for this genre.

Im sorry if I'am asking too much, but theese things have been bothering me
Best
