S.T.A.L.K.E.R. 2 - Facebook Q&A

There's a very short S.T.A.L.K.E.R. 2 community Q&A on their Facebook page.  A sample:

Q: What will be the biggest difference between S.T.A.L.K.E.R. 2 and the previous games, if any?
A: In brief, S.T.A.L.K.E.R. 2 will offer new story, new set characters (with some good old ones) and, of course, the new engine powering it.

Q: Will there be more of a survival element to STALKER 2?
A:Yes.

Q:What features have been removed/compromised in the PC version due to the multiplatform release?
A:Since we develop primarily on PC, you won't see any compromises in the PC version. The key difference between the PC and console versions will be the beauty of graphics (meaning PC will offer more of visual effects).

Q:Will there be any new kinds of interaction with NPCs?
A: How do you mean? It's difficult to answer this one.

Q:Will Sidorovich be in S.T.A.L.K.E.R. 2?
A:I will refrain from answering this one for now.

Q:Will the faction wars return?
A:No.
