More of the same info with the exception of these two tidbits:
-there will be extensive interiors, ie; caverns, castles, caves etc. Novigrad in particular will feature lots of interior space. I suspected as much, but it's still good to hear. I love nothing more in an RPG than exploring creepy and elaborate interiors, and RED engine was strongest in these spaces.
-wildlife will vary in each region.
I don't want to come off as elitist, but I think a lack of diverse English speaking skills is causing them to fall back on a predictable checklist: "we are making mature game, world is 35 bigger than Witcher 2, there will be monster hunting, etc.." The interviewer asked very good questions, the dev just wasn't doing a good job of answering them. Meanwhile, interviews in German, Russian or Polish tend to be much more insightful. It doesn't benefit them to feed one demographic new and interesting bits, while feeding the other the same stuff they've known for months. Merica probably is their biggest market. It's time to hire a native English speaker to do the interviews.
