I am thinking about getting the Pro Edition but for how many maps do I get for the extra $50 and how many maps come in the game ? I am getting this for PS4 if that makes a difference.

No clue how many maps are in the game but every other recent CoD has had 4 packs of 4 maps + a map for the bonus mode.

Yea the 4 dlc's w/ 4 maps/1 zombies or extinction mode map has been the same since Black Ops so I would bet it's the same this year.

Ahh ok cool thanks I have never bought a Season Pass for a CoD game before but this game looks awesome so decided to pick it up.

Apparently the Season Pass will also include the entirety of the Zombies mode. So there's that to take in.
