Translation:
Mattias Filler drew my attention to this thread. There seem to be some more of them, so here's a short statement for all that are interested:
1.) I (Michael Hoge) was not involved in the development of Risen 3.
2.) Indeed, I locked myself in for two years to work on a new concept (not Gothic). We are already developing a prototype of this concept with a small core team since the beginning of this month.
3.) Before someones asks: I can't give any informations yet. We need some time with everything (...) but those who are interested in this topic, will not have to wait long for more information.
