Sword Coast Legends [official site] is not a new Baldur's Gate, but the co-op-packing RPG does look pretty fun.

Sword Coast Legends is built on the Dungeons & Dragons Fifth Edition rules, and returns to that fantasy land made famous (in PC games, at least) by Baldur's Gate games. It's due to arrive for Windows, Mac, and Linux on September 8th.
