So after reading everything that was said here I felt the need to expand upon my original post slightly.
To Dark_Ansem's point of DLC being synonymous with expansion pack; I mean yeah basically I agree. I used the term DLC simply because that's the first thing that comes to mind and it seemed to me like the most appropriate way to talk about it but looking back on it I realize DLC as a term might have a negative connotation (mainly via EA, though there are plenty of other shoddy devs who've done harm too).
And to basically everyone elses point here: I wouldn't want Larian to put out a $10 pink hair DLC. The notion of such a thing is entirely preposterous. As it has already been stated, the value of the content to the price being asked are not on equal footing in a pink hair horse armor DLC. I didn't go into detail in my original post regarding what additional content might look like nor what price Larian might ask for it, because it would all depend upon what makes it into the game in the end!
As some have stated, I think an additional Act with new quests/story/characters/items/spells and possibly even new mechanics would most likely be a welcome addition 8-9 months after DOS2 had been released. Now, as Raze mentioned (as I figured would be the case) they have no plans moving forward because everything is all so up in the air with the focus being on the core experience.
Personally I wouldn't complain if Larian decided to add a few small pieces (Bards bards bards....) after release as DLC but I certainly wouldn't be on board with paying $30 for a skill tree either. That's absurd. Though I also completely understand if they decided "naw, no enhanced edition for DOS:2 we're instead going to move onto our next project". As long as the core experience is everything they intended to produce, then I'm pretty sure we'll all be more or less happy.
On a final note I would love if Larian revisited the idea of "what do we do next?" with their fantastic community once DOS:2 is completed. I see a lot of potential both for interesting DOS:2 expanded content given the features (Game Master Mode for example) they've already announced, as well as potential to take some of those ideas and simply march toward the next title as well. In my limited experience the folks at Larian are some pretty swell people and I'm sure they'll do what they feel is ultimately the right thing to do for their community.
