I thought it was confirmed that there are supposed to be only 3. O_o
Swen talks about 3 acts, but others on the team have clarified that in Swen-language, what he is referring to is general story arc progression, not the tangible acts in game which even call themselves acts, and which any sane person would understand the importance of not conflating: Swen also calls D:OS2 a three act game, for example. The fact that others felt the need to clarify this when it came up suggests that the game will indeed have four acts, or some other number that is not, in fact, three.
Gotta admit though... now that it's been voiced, I'm kinda scared about Grey Ghost's second paragraph too. Like, don't get me wrong, I want it to be an excellent game, and I want it to do well if it is... but if it remains the thoroughly unsatisfying trash fire hat it looks like right now, I don't want other games in the industry deciding they need to tar themselves with that brush too.
