If we were to rank this rumor on the probability scale, we'd be forced to put it on the low end.
Even so, considering the fact that we've been waiting for many, many years, we suppose the end might finally be in sight. According to an "inside source" as cited by GotGame , Diablo III might launch in November of this year. That's right, November 2011. Of course, the source says they're "pushing" to hit that release window, with Blizzard employees "working from 9 a.m. to 2 a.m. daily to finish polishing content." We haven't the slightest idea what GotGame is talking about regarding Activision Blizzard's "common" secrecy ploy concerning new titles (that's a…bizarre observation), but we'll let that slide. The bottom line is that Diablo III might finally be on the fast track.
There's still no knowing whether or not the long-anticipated RPG will arrive for consoles as well as PC, but multiple pieces of evidence have suggested D3 will indeed arrive for the PlayStation 3 and Xbox 360.
