On the topic of when it will come out...I only care cause I'm awaiting the windows beta. But my guess is that now Jeff's finished his book he'll be able to start on Geneforge 3...which will come out sometime in March 2006...yes, 2006.
Dolphin, the Mac Betatesting will have probably started a good few months ago, and will continue up until the moment it is released out to the public...the same thing will happen for the Windows version, after its released for the Mac of course.
Can't wait, hoping to get into the beta testing to break up some of this boring uni work.
