I have revised our Call of Duty: Ghosts estimate and it was pretty spot on.
(100%)
[Week 45] CALL OF DUTY: GHOSTS (ACTIVISION BLIZZARD) - 775,000 / NEW
[Week 46] CALL OF DUTY: GHOSTS (ACTIVISION BLIZZARD) - 186,000 / 961,000 (-76%)
[Week 47] CALL OF DUTY: GHOSTS (ACTIVISION BLIZZARD) - 156,240 / 1,117,240 (-16%)
[Week 48] CALL OF DUTY: GHOSTS (ACTIVISION BLIZZARD) - 207,799 / 1,325,039 (+33%)
[Week 49] CALL OF DUTY: GHOSTS (ACTIVISION BLIZZARD) - 211,955 / 1,536,994 (+2%)
[Week 50] CALL OF DUTY: GHOSTS (ACTIVISION BLIZZARD) - 167,444 / 1,704,438 (-21%)
[Week 51] CALL OF DUTY: GHOSTS (ACTIVISION BLIZZARD) - 179,165 / 1,883,603 (+7%)
[Week 52] CALL OF DUTY: GHOSTS (ACTIVISION BLIZZARD) - 136,165 / 2,019,768 (-24%)
According to Chart-Track, Call of Duty: Ghosts sold 1,991,994 units in 2013. We were off by only 28,000 units.

Thanks to MCV magazine we later learn that Destiny did around 417,100 (95%) units. Maybe Titanfall was a bit underestimated.
Nice.
So considering that the Ghosts figure is likely the most accurate, this means that these three titles must have sold at least 680k together (which would put AW at 775.2k according to the +14% comment from Chart Track).
So, probably a bit of underestimation for TF, Destiny and WNO.
