Also coming tomorrow is the first Map Pack, which includes maps Westmorland and Camborn, for £2.99 GBP and US $7.99. No word on the map pack or update outside of Europe; we've contacted Sony Computer Entertainment America for information on the status of the update in the US.
[Update: Included US information care of Sony's shiny new blog. Thanks for the heads-up!]
