0% of BG2 was in Baldur's Gate, but most of it was in Athkatla, and its surroundings including three of the strongholds. Unless you're making the point that we're presuming a lot when we say we'll be in BG. I think just based on the statements Larian have made, and the plot threads we've found in the EA, that we'll be spending a significant portion of at least the next act in Baldur's Gate.
