Beamdog teased back in January that they had an upcoming project for 2015, meant to bridge the gap between Baldur’s Gate: Enhanced Edition and Baldur’s Gate II: Enhanced Edition. They mentioned that fans should probably watch the blog for an announcement in late spring, and it looks like it’s here.
It’s a little later than late spring, but there’s a countdown on the Baldur’s Gate official website now. Adventure Y, they called this upcoming project, might be revealed in about 10 days’ time. Some screenshots and information appear to have been leaked on the forums, but perhaps a little more digging will yield better results? Ten days doesn’t seem like a very long wait.
