Call of Duty: Black Ops 2 will no longer feature region-based matchmaking in multiplayer, and will instead rely on latency and ping, Treyarch game design director David Vonderhaar confirmed in a series of tweets spotted by Charlie INTEL.
In response to a question over whether the new entry in the Call of Duty series would feature region-based matchmaking, Vonderhaar first stated "something new and improved over that. Will tell you more next week after I confirm it actually makes it." He later confirmed the upcoming title's matchmaking system is "not region based anymore. Latency/ping based exclusively."
Call of Duty: Black Ops 2 will be released for PlayStation 3, PC, and Xbox 360 on November 13th. A Wii U version is due at that console's launch.
