A Baldur's Gate countdown clock has mysteriously appeared on the Baldur's Gate: Enhanced Edition official site, leading to inevitable speculation that Baldur's Gate 3 will be announced. We'll have to wait until tomorrow for the news, though, that's when the clock reaches zero.
TheEnhanced Edition of Baldur's Gate was originally announced via countdown clock, and the game was scheduled to come out this summer, so it seems likely that the clock is counting down to the release of the game. Or perhaps an announcement of the release date. Or perhaps something else entirely. It's very hard to say, until the clock gets to zero.
I suggest you spend every moment between now and tomorrow morning staring at the clock and waiting; that's what I'm going to do.
