One thing Mike mentioned was that at one point he was working on a 4th Corporate War supplement named "Aftermath" ... while it was never published he and CDPR are using some of the the ideas from it.
Another thing he made clear is 2077 is effectively an expansion of previously published material ... not an "alternate" history.
I was very happy to hear him stress concerning CP2077 (Mikes own words) - "It won't be a shooter with some role playing stuff in it. It's gonna be more, it's role playing an things happen that matter. But, with a lot of really cool shooter and netrunning and other things tied into that."
He also made some comments concerning the "Lifepath" material in CP2020 (Mikes own words) - "One of the things I can tell you about 2077 is that these guys really went over the rules of Cuberpunk and tried their best to find a way to apply them. Which means some of the elements of Lifepath and things like it are kind of built into it. I can't really get in to how they're doing life stuff, but it's a really faithful feeling of what's going on."
