Capcom Japan has just announced that Dead Rising 2: Case Zero, the prequel episode of Dead Rising 2 on Live Arcade only expected for tomorrow, was postponed to later date due to some problems with the demo version game, which seems to propose inappropriate content (probably because too violent) to a free version. It is not clear now whether the postponement will involve only the Japanese Marketplace, or if the game will be delayed even by us: we will update as soon as there will be news.
