I am optimistic as well but I have been burned before so I can't help but have that small amount of doubt. I don't mind not being able to play after the main quest. FO2 has that option and I have only played after the end a couple of times out of the countless times I have played it.
I've never been burned by Obsidian before. Well, unless you count fire-breathing bugs.
At any rate, I knew Todd was, err, highly exaggerating once he came from nine endings to more than a hundred. Seriously, they'd rather not bothered at all than sell "You good/neutral/bad, and you make two things a minute ago!" as an epic ending.
