Translation: When do you think the Revolution map pack will come out for the PS3?
Answer: "I don't have an official release date yet, I'm afraid. Traditionally it's been about 30 days.(After the 360's release of it)" <- Treyarch
If you have a Season Pass, then you will get all 4 Map Packs free when they are released. When you bought the Season Pass, you bought all 4 Map Packs.
