Chris Taylor of Gas Powered Games has told CVG that thehe made about Dungeon Siege 3 being a single character role doesn't mean the game is actually in development, and that nothing official is going to be made as the team are at the idea stage.
“We have not made any official announcements, or have any official plans, but we are kicking ideas around, and that’s no secret,” said Taylor.
“The example I gave was the multi-character parties… saying I was done with the big parties, because it really took the focus away from the main hero. In fact, in Dungeon Siege, it was hard to really have a ‘main’ hero, so-to-speak.”
So it'll be quite awhile until we hear anything more about Dungeon Siege 3, we think.
