Gamespy found out that the a GameCube version of Baldur's Gate: Dark Alliance 2 hasn't been completely ruled out by Black Isle Studios. They found the following quote on the companys official website:

"Unfortunately right now there aren't any plans on doing a GameCube version, but that doesn't necessarily mean it won't happen. I worked on the GameCube version of BGDA and enjoyed working with the GameCube, and everyone at Nintendo. Our current BGDA 2 team isn't big enough to handle 3 platforms at once, but who knows what will happen down the road."

We might be getting a BGDA 2 after all. We will keep you updated!
