I also would prefer to avoid anything about the end (or middle) of the game (its style or content).
Lar mentioned that it would make more sense if they were going to release any modding tools, that they be included as part of a multiplayer addon than just for single player. While neither are more than a hypothetical possibility at this point, Larian is at least not opposed to the concept of addons.
Since DD, budgets have gotten higher and development times longer, so an addon (working with basically the same game engine) should be faster/easier to develop, and if successful, help fund the next full game (perhaps exposing more people to D2:ED, as well). It shouldn't delay development significantly, as the writers, artists, etc could work on the addon, while the majority of the programmers concentrated on the next game engine. In any case it may be a tad premature to start worrying too much about addons...
