Sony has said that the SOCOM: Confrontation expansion pack Cold Front will be released in Europe on 7th January, although pricing is still to be confirmed.
Cold Front came out in the US last week and consists of a new area in Eastern Europe populated by five new maps, new weapons, new Trophies, a new specialisation system, and more importantly SNOW! And SNOW EFFECTS! SNOW GEAR!
There are more details on the official PlayStation blog, where you can also read a comments thread full of people complaining about discrimination and things like that. SNOW!
