Resident Evil 5 was updated last night with a v1.02 patch. Taking a quick look at RE5's Trophy list, we've noticed that ten new Trophies, the ones linked to the upcoming DLC, have been added. The new multiplayer DLC isn't out yet and we're wondering if this new revelation means we'll be seeing it very soon -- perhaps as early as next week. But don't get your hopes up; Japan is the only region that has a specific release date and that's been delayed to April 9.
Other than the new Trophies, there weren't any other noticeable changes to the game. We've contacted Capcom for full patch notes and will update as soon (and if) we get them.
