I hardly find it surprising that there were a lot of questions to which he didn't give a concrete answer, after all, the game is not finished yet, so Bethesda may want to be cautious about promising anything they aren't sure they can deliver, which sounds like a wise choice, considering how many times players have been dissappointed with games because the developers failed to deliver all that was promised. And some things maybe are done already, but Bethesda feels they're best left to a later time to answer. Listening to the podcast, I got the impression that Todd was being quite careful not to give out more information than Bethesda is ready to give or make any promises that could potentially not be fulfilled.
Myself, I'm glad that we did get some new information from it, and more detail on some things that we weren't sure of before. Some of the information was pleasing to hear, some of it less so (The lack of spears probably the highlight of the negatives to me.) But I'd rather be told the truth of what Bethesda is doing with the game than only what would please me about it, and the way those parts were worded still left open the possibility that those things players want which currently aren't in the game might be implemented later on, so Bethesda can still turn around and say "Actually, we decided to put spears in after all."
It's quite a shame, because the Fable series is quite good but always falls short of the massive hype Molyneux creates. He is, in a way, dooming his own game. I'm glad Todd isn't hyping up Skyrim too much. Besides, I'm plenty hyped for the game already.
To be fair, since they've been able to get as far as Fable 3 already, it seems to me that despite each game producing dissappointed fans complaining that it failed to live up to the hype, they series still enjoys a fair amount of success, and I'm not talking a minor niche market success, Fable is the kind of game that's constantly being hyped up at major events.
