Ever since we saw the Battlefield 3 Steelbook edition boxes which had room for two discs, many wondered wheter the game would ship on two discs. According to gaming outfit Gematsu, a poster for Battlefield 3 at a Japanese gaming shop shows the fine print specifying that the game will ship on two discs on the Xbox 360.
This is hardly a surprise, as games are getting bigger and bigger in size, with the DVD format showing its limits with 7GB of storage. The PlayStation 3 version will ship on Blu-ray, which has plenty of room, but it’s unknown whether the PC version will ship on two discs as well. It’s not hard to imagine it shipping on two DVDs for PC users to install, while the Xbox 360 could be split into a singleplayer and multiplayer disc.  
DICE has extensively showcased both the PC and PlayStation 3 versions of Battlefield 3 over the past few months, but we’ve still yet to see any details/footage from the Xbox 360 version, which is likely to be the best selling version of the three — pre-orders for the Xbox 360 version are double of what they are for the PS3 counterpart.

可能会是这样的 “一张玩单人模式，一张则是多人联机”
