Brian Fargo isn't the only one visiting PAX South this weekend. A whole bunch of folks from Obsidian are also attending to promote Pillars of Eternity. Unlike the Bard's Tale IV announcement, this panel is being streamed, and it's about to start:

What a weekend!

Update: And it's over! The gameplay demonstration was pretty short - a well-choreographed, action-packed dungeon crawl. The real meat of the panel was the Q&A session, which was surprisingly entertaining and information. I recommend watching the whole thing.
