We know that Microsoft will be getting the Call of Duty: Modern Warfare 2 Resurgence Map pack earlier than Sony and although we know the arrival date for the Xbox 360 version, we still do not know when the Resurgence Map pack for the Playstation 3 will be arriving.
Based on the last few update, it is estimated that the Playstation 3 version will only be arriving 1 month after the map is released on the Xbox 360. Since we know that the Xbox 360 version was released on the 3rd of June, some fans have predicted that the 3rd of July will be the arrival date for the Playstation 3.
However, Attackofthefanboy.com seems to think that the 6th of July is the more likely date. That is because the 6th falls on a Tuesday and we all know how much Sony likes to have their updates on a Tuesday.
