The first paragraph in Giant Bomb's review sums of the new COD Ghosts game perfectly.
"There are no UAVs to shoot down. Strike packages are back, and the dolphin dive has been replaced with a knee slide. You can lean out from cover. All of the launchers are free-fire, and knife kills now come with an annoyingly forced kill animation that leaves would-be stabbers open to counterattack. Theater mode is history. Headquarters mode is nowhere to be found. Same with Hardpoint. Call of Duty: Ghosts continues the weird trend of reversing/removing changes made by the other development team(s) that ensure that Activision's dominating shooter franchise makes it to shelves every November, but it also represents some of the largest multiplayer changes the series has seen since Call of Duty 4 redefined console-based first-person shooters for the previous generation of consoles. Here's the catch, though: many of those changes just make me want to play Black Ops II, instead."
While it's apparent some websites got "paid", It seems ACTIVISION felt there was enough momentum from next gen consoles plus a large install base on current gen, to just say, "new COD game on Nov 5th"!
