LFN site JKII Mod Central has interviewed Raven's Christopher Foster, the design lead on JKII. He's interviewed not only about modding JKII, but lots of general (sometimes interesting!) questions too.
Also, Elited.net has an interview with Kenn Hoekstra, talking about the use of the Quake III engine, some story bits, and the whereabouts of Kyle's ship, the Moldy Crow.
