Just wondering here, but has anything been confirmed about a sequel to kcd?
After all DLCs will be released. Then you can ask this question. They mentioned they have no features nor talk about it in WHS, instead focus on bugs and DLCs.
THAT could keep them BUSY for a couple years 
Warhorse Community Manager recently made a post about KCD2. It has been removed since.
Here’s a relevant snippet:
The full fledged development of KCD2 can start after the release of the last DLC A Womans lot and modding support for KCD.
But, since the post was removed, we should take that info with a grain of salt.
