Okay, so assuming Act I Part X ever gets published, how long do you figure Act II Part I is going to take?
AFAIR, the dev spread out the game into three acts where the actual nasty is going to be happening in Act III, so if we take the current length of time between releases (two years, it's looking), and assume they will stay the same, Act III Part I, the foreplay to the foreplay is going to be released in some 40 years. If the releases draw out even more, we might be looking at the release in 60+ years.
I know! The dev is aiming for the "longest time in the making" achievement.
