On Diablofans they have images of the BradyGames Diablo 3 Strategy Guide! POSSIBLE SPOILERS (because it shows some new monsters and their locations)
Take a look at the HP of some of the Inferno Mobs, some achievements and more monsters. This is ridiculous!
Also, there was some debate on whether the Skeleton King and other bosses would have new abilities in later difficulties, this image from the guide may suggest they wont?
So what does everyone think about all of this little bit of new info? Do you think they are hiding some of his abilities in later difficulties?
