I totally agree with you Veldmaarschalk. They should basicly port the game into the clausewitz engine and in the process better the game. Stop instant realm disintigration few years after you press start. Make some of the other laws useful rather than just feudal contract. Also the strategy part of the game could use something new, maybe becoming more detailed or something. The character system must be treated with care though as that it was made the ck game so special.
Edit: forgot to mention that they should try to maintain the dark humor they had in many of the event description. So instead of tearing your hair off and reloading when your monarch becomes crazy you will simply laugh and try to cope with this interesting development.
When suggestion a simple port, it should include some of the really cool new developments in later titles, like Rebels with a cause, strength of heir, having different vassals back different heirs (with a good chance of civil war if you back an unwanted one), province and national decisions, tribes/pagans/republics playable (with different styles of ruling the nation, a bit like it was done in Rome) etc.
There are sooo many cool things that could be added to the game to make it absolutely magnificent. And I believe that all the problems with HOI/EU/Vicky series where some havee trouble dealing with the transition from deterministic/event-driven game to a more sand-box game, CK never had that many events that were specific. So the transition to the new engine and way of development should be easy.
As long as they keep the basic game the same as before and just fix bugs/features and add new cool stuff, they can't go wrong ... at least in my opinion
... and with more and better modding possibilities, the sky is the limit
