Perhaps a little overhyped but that comes as a bonus when hands-on impressions have been so good. Everyone who tried it is praising it. That must mean something.
It's a 95% Meta incoming and will be absolutely huge. Between all three versions it should reach 10 million in 2014 (and with the sequel likely being on PS4 it will grow to the extent of going head to head with COD in popularity).
Also the timing of release couldn't be more perfect by releasing so close after the disappointments with Call of Duty Ghosts, Battelfield 4 and Halo on a decline.
