Forum:Questions Regarding the CoD Timeline

Greetings, readers.

I have a couple questions regarding the nature of the Call of Duty timeline, and I would like to ask them in this post. First, here is what I believe to be the Call of Duty timeline, with information courtesy of Wikipedia and this wiki (If there is a slash between the titles of 2 games, then that means they are set concurrently. Ghosts and Advanced Warfare are omitted because they contradict canon):

My * primary questions are: Creepypastafan206 (talk) 02:41, August 14, 2016 (UTC)
 * Call of Duty/Finest Hour/2/Big Red One/3/World at War (1942 - 1945)
 * Call of Duty: Black Ops Mobile (1967)
 * Call of Duty: Black Ops/Call of Duty: Black Ops DS (1968)
 * Rightful King (1973)
 * Call of Duty: Black Ops: Declassified (1975-1979)
 * Call of Duty: Black Ops II (1986-1989) (80s thread)
 * Call of Duty 4: Modern Warfare (2011) (Mobile)
 * Call of Duty 4: Modern Warfare Remastered (2011)
 * Call of Duty: Modern Warfare 2/Call of Duty: Modern Warfare: Mobilized (2016)
 * Call of Duty: Modern Warfare 3: Defiance (around the same time as MW2's final missions, 2 or 3 days leading up to MW3)
 * Call of Duty: Modern Warfare 3 (2016, shortly after MW2)
 * Call of Duty: Strike Team (2020)
 * Call of Duty: Black Ops II (2025, 2020s thread)
 * V.E.R.S.I.O.N. (2037, Singapore thread)
 * V.E.R.S.I.O.N. (2063, Zurich thread)
 * Call of Duty: Black Ops III (2065)
 * Call of Duty: Infinite Warfare (presumably long after BO3)
 * 1) Where is Call of Duty Online in the timeline?
 * 2) Can the different story arcs (WWII, Modern Warfare, Black Ops, Infinite Warfare) really be reconciled like I have?
 * 3) Is there any material or any games I am missing?
