Given that Larian is a small studio I think their plans are somewhat fluid; so some of it is likely to depend on reception of the game et all. Don't forget they still been thinking abuot ways to improve dragon commander. I.e, I suspect if reception is over the top (sort of like witcher 2) they will add considerable free content but if reception is totally negative (no clue - maybe presales have already been over the top) they might rethink that they need to go in another direction. Being a small studio has a lot of advantages with regards to being able to 'go with the flow'.
