According to some new images that arrived on Steam Forum, Modern Warfare 3 will be getting 5 more prestige levels. You guys can check out the image below, and there is room from prestige 11-15. Infinity Ward's Robert Bowling has confirmed on his personal Twitter account that 400 new levels and five prestiges have been added to PC version of MW3. This addition will be made to the console version in coming days.

On Twitter, Bowling wrote, "Added 400 new ranks of 5 new Prestige levels in Modern Warfare 3 on PC in latest patch. Expect the same on consoles soon for everyone! #MW3"

Interestingly, 10 new prestige emblems have been added to the game files as well, according to Charlie Intel (see image below). Bringing the total number of prestige levels to 20, not 15. We still don’t know if levels 15 through 20 are accessible or not, but we’ll keep you posted as we learn more.
