Well, as much as I loved the games, I must agree that a third BG would just be bleeding the turnip patch dry. As an old D&D player from the late 70's until WotC took over TSR, I will say this....there is no shortage of settings for another game. They could do Sea of Fallen Stars, Moonshaes, Cormyr, or even a (non-drow) Underdark game. They could base it in Waterdeep, Hillsfar, Zhentil keep, Westgate....yadda yadda. They could even do a Dragonlance game (they ruined Temple of Elemental Evil and Pool of Radiance in my honest opinion).
Baldurs Gate should be left alone. The characters are of stupidly high level and I think it gets a bit unimaginative at those levels. And since it is supposed to be a prequel, I don't think any but the old & decrepit NPCs should get a cameo and they should refrain from using Elminster and Drizzt in every game....I never cared much for Drizzt to be honest with you
