Some news about expansion

[Jamers]

Seems to me from what I've been reading in interviews and whatnot that this will essentially be a whole new game, just that the engine / some graphics, units, etc. are carried over. Anyone know for sure?
In the interview it says you can no longer use the rage spirits, and the guy being interviewed (Dmitri something) didn't really answer the question as to whether we can carry our heroes from 'The Legend' over into the game, but I imagine you need to start from scratch, as this game is about the princess and her dragon.

Also, on the 1C website, it says "sequel to King's Bounty..." blah blah. Whole new game, then?
