There is no confirmed release date, it is early April. They will announce when it will come out so just don't worry about it until a release date is announced. Infinity Ward says early April so i estimate April 10-20. The Game of the year edition came out on the 1st of April and there is a free code to get the maps for free when they come out.
That is so lame, i know what infinity ward said, early april is from 1st-15th though... think of it cheapskate, early is the earlier part, lol... not in the later half of the month, every day i am gettin up early to check...
You don't need to wake up that early to check, they would announce something so publicized. It will most likely come out around the 10th of April. If you want to be a smart *** about it, between April 10-15. It would be wise to extend the wait to the 20th though. Good slowly made maps are better then crappy quickly made maps.
Hahaha great aps, though I only played on them for an hour before letting the game collect dust. I should probably give it a shot again, they looked amazing
