According to a report filed on 1st March 2010 by Activision Blizzard, there seem to be more than 1 Diablo game other than Diablo 3 in development. It can either be hinting that, or they are already planning a Diablo 4. A Diablo 3 expansion is more or less inevitable, but it cannot be termed as a sequel. Will the new rumored MMO be a Diablo MMO with a first person view? Yet, Blizzard has said the new MMO will be a totally new IP. We shall see.
Below is the new Male Wizard which was just revealed recently.
