Following rumors from earlier this afternoon, Infinity Ward's Robert Bowling officially announced via his Twitter account that four hundred (400) new ranks, making up five new Prestige levels (11-15), have been added to the PC version of Call of Duty: Modern Warfare 3.

In addition, Bowling notes that the new Prestige levels will be added to consoles (Xbox 360 and PlayStation 3) "soon," but no official release date has been provided at this time.

For comparison, Call of Duty: Black Ops, the previous title in the popular first-person shooter title that was released in 2010, had fifteen Prestige levels as well.
