Gamesfire interviewed STALKER's Oleg Yavorksky recently and the english translation of the Q&A is now up. Not much new info as far as I can see, though apparently it will have Dolby 7.1 support:
<blockquote>GF: Lets come to some technical questions: Concerning the graphics engine, we have seen lots of screenshots showing the interior parts of S.T.A.L.K.E.R. using DirectX 9. When will the whole world be presented in the DirectX 9 format? Or is it already DX 9-optimized? And in which format will we able to “hear S.T.A.L.K.E.R.”? Will there be a 7.1 sound system support?
Mr. Yavorsky: We’ll show you more of DX9 once it’s possible. As to the sound system we can already say that it will fully support 5.1 sound system. Closer to the release it will be clear about 7.1.</blockquote>
I'm still looking forward to this game, but I think the potential Q&A information has been exhausted at this point.
