I?ve been studying The Divine Comedy in my literature class, which we all know is where the whole Heaven/Hell idea comes from, and my teacher told us that in that book, Lucifer (aka The Devil, Satan, Diablo) has got 3 mouthes, which he uses to eternally chew Judas and 2 other guys.
I?m not saying we will see Diablo chewing guys, but it can perfectly be an explanation for his 3 mouthes!
Whoa is that really diablo's new form? you said about it being in developement so the other two arms are still part of the initial model? Wow they really have changed his look of him, but im not sure i dont know if blizzard would reveal it that obviously, come on he is gonna be like the main boss aswell!
