Just found a site that said PS3, pc, and PS4 on May 1st 2014. so that should be the date.
Season pass holders on xbox got it a month ahead of the second DLC drop on the 7th of March, if PS season pass holders get the same deal it should be around the 7th of April or shortly afterwards
The Ripper will be available on April 8th and the Devestation map pack on May 6th. These dates are the first dates after the original 30-day delay that the Playstation Store updates
Your calculations are off....March 6th + 30 days = April 5th. So the earliest it could come out is Saturday, but I won't really be surprised if it takes a few extra days.
as for Devestation: April 3rd + 30 days = May 3rd
Pretty much, what can be assumed is that we will recieve the Ripper next week. That's the bet, clan wars are going on meow, no I think they don't want people running the Ripper yet, so if anything, this upcoming Tuesday, we should get it. Idk
infinity wards twitter says april 5th for season pass holders on psn... but they also said we were supposed to get dropzone monday, yet didn't get for a couple days later, so who knows.
