Baldur's Gate 2 came out over a decade ago, so the series seems due for a revival or at least an homage. A mysterious Web site appears to tease a new game in the series; it carries the series' skull image and several references to the lore, but no official announcement has been made.
The site BaldursGate.com launched yesterday featuring the familiar skull iconography and music from the original game. The site also quotes from the series: "The Lord of Murder shall perish, but in his doom he shall spawn a score of mortal progeny, chaos will be sown by their passage." Plus, Eurogamer points out that the source code of the site is packed with lore easter eggs.
GameBanshee received a statement from former BioWare designer Trent Oster, currently of Beamdog, who confirmed that an announcement is forthcoming.
So it appears that Beamdog is working on a Baldur's Gate something, but don't pin your hopes on Baldur's Gate 3. Beamdog previously worked with Interplay on an HD re-release of MDK2, so it could simply be a revamp of one of the classic titles.
