That's not really what he said Pop:
We felt coming out of Oblivion that Knights of the Nine - that $10 one - was a good sweet spot, not just in terms of what people want to pay, but for us creating it. Whereas Shivering Isles, it's a $30 thing - people bought it, it did great - but it wasn't great in terms of how long it took us to do it and get it out.
So we went into Fallout 3 with this $10 price at this pace. I can tell you that pace was fast. We had two overlapping DLC groups, tiny groups, and we did that, and the audience, they liked that rate of them coming out but it was hard. I don't know if we're going to be able to do that again.
I think at the end of the day we just want to have something that is really high quality and maybe not put so many out.
EDIT : So basically, same model as F3 but with less DLCs overall and higher quality. Definitely not Shivering Isles-sized expansions, since they would take to much time.
