I just came from playing Call of Duty: Ghosts Multiplayer and I have used the new DLC weapon "The Maverick". The Maverick is a AR gun and a Sniper Rifle that came with the first DLC pack for COD:Ghosts. After using it for the 4th time I realised something; that the iron sight of The Maverick is pretty similar to the Reflex sight of a gun on COD:Advanced Warfare the EM1 Quantum. Look at the similarities:
See the similarities? And the Quantum Reflex also has similarities with The Ripper a AR/SMG that when the player pushes the R3 button (B on XBOX) the iron sight turns into a futuristic Reflex sight. (See below)
See what I mean, the sights are pretty simillar. But the point is it's coincidence or that Infinity Ward was teasing COD Advanced Warfare all this time? I think it's true but with no confirmation of the 2 studios its hard to tell.
