Well, it would be fair to begin speculating about the fate of BoD with the recent news about Codemasters. They officially announced that they would switch their focus exclusively to racing games. Obviously because their racing franchises are the most successful ones. So it would be a logical step for them to sell full rights to somebody else. But since they told GOG that they "no longer hold the distribution rights" it doesn't necessarily means that they don't hold the intellectual property right. They might've transferred only the distribution rights to somebody who has better understanding of the market and has better means of distribution for this particular genre of games.
If that's the case it won't take long until BoD reappears here again. Or it could be a different scenario. Maybe Codemasters only had distribution rights but the IP belongs to somebody else.
The corporate fascists would never let a dollar making opportunity get through their greedy fingers. I can almost see it now: BOD by EA
Mega-corps like EA or Sony, or etc., will never be interested in such projects like BoD. Because BoD is part of a history, it wasn't successful back then, today nobody knows about it and it doesn't have any interesting lore or a universe associated with it. There isn't much story here, it's about a hero who goes on a quest. There are knights and gnomes and orcs and some beasts that you can find in any other fantasy game. It's the mechanic that makes the game interesting, but you can copy the mechanic easily. Simply put - there's nothing to buy here. I'm sure even GoG doesn't make much money from the sales of BoD but we love this game nonetheless.
