Momentarly I'm actually leaning more towards AAA. Mainly because its early to give out definite roles for a kickstarter.
It's actually not too early, because this Kickstarter was postponed from April if you recall.
That's assuming by that point they already had something definitive.
And thats not what I meant. If theres anything Obsidian has proven to do differently during Kickstarter production is that they give themselves as much time as they need with important decisions including lots of figuring out who on the team is best for what.
Aside from Sawyer (who was pretty obvious) the actual roles people had on the Eternity team weren't fixed till several months after the Kickstarter. Remember, people assumed Avellone was creative lead for a larger amount of time.
It would be a more than a bit surprising if they let all of that freedom go and try to approach Kickstarter2's production like any of their AAA projects.
Edit: Granted this could turn out to be some Avellone Pet-Project Kickstarter, but I personally doubt it.
