So far, I have found only ONE video of Fable 2 at PAX '08: link

Seems nobody wanted to play it :(

I found a link on YouTube to an article about Fable 2 at PAX. Apparently it's still got a lot of bugs. I'm worried about them fixing them all by the release date.

EDIT: not worried anymore, "The Gravehound" from the NoobToob forums said that he was speaking to the demo dude and apparently it's the same demo from E3, and that was like, a month or two ago.

Also, news on magic. The Mana bar has been scrapped. Lionhead says "you can use as many spells as much as you want, but you get a lot more experience if you mix it up"
