A tweet from Sledgehammer Games co-founder Michael Condrey could suggest the number of ranks and prestige levels in Call of Duty: Advanced Warfare.
As noted by MP1st, the following post looks likely to be a reference to ranks and prestige, and if true would take prestige levels beyond the regular 10 in a Call of Duty game.

Condrey has said before that the team has yet to decide between 10 and 15 Prestige levels.
Call of Duty: Advanced Warfare is due for release November 4.
