I sincerely doubt that.

All I can find is adventure Y, that as far as I know is a connection between bg1 and 2, and completely uneeded.
And that they want to make BG3, but WotC thankfully isn't budging. They should leave the BG series the **** alone, it's a finished deal.
Frankly the only content I liked from them is the NPC Baeloth in BG:EE, the rest is horrible. I haven't played BG2:EE, nor do I plan to(mod incompatibility), but I doubt that their writting improved.
