Any guesses / ideas on when BG2 complete will be released ?
I suppose this is speculation in and of itself, but seems the stars are aligning to complete the Baldur's Gate series.

Hard to say for certain, as GOG has been mixing things up of late, but if things follow the general pattern, it should be this coming week, likely on Tuesday.

Or maybe they are saving it for last.

The next Atari/Hasbro release is the last. They said there were 7:

1) BG1
2) IWD1
3) Planescape:Torment
4) ToEE
5) NWN
6) IWD2
7) ??? (if it's not BG2, there's something seriously wrong).

GOG has a sense of humor.
Space Rangers?
Well, anticipation is half the fun, I suppose.
Back to BG 1 !
