Dante may be a different man in DmC - Devil May Cry, but his trademark weapons have returned, and they're still pretty recognizable. New screenshots show us more of Dante and his arsenal; he's missing his coat in a few of these images as well. In addition to the screenshots, you'll also find concept art of his weapons.
Rebellion, Dante's sword of many years, still boasts the same basic design as before, with the exception of a smaller handguard. Ebony and Ivory are obviously still black and white in color, with a few but subtle cosmetic changes. The idea behind all three of these weapons is to give them an old appearance, like "they were crafted a long, long time ago." Rebellion maintains the same backstory of being Sparda's sword, while Ivory and Ebony's origins remain unknown.
Maybe having the same weapons as Dante-past validates the new one, somehow. DmC will be out some time in 2012, for Xbox 360 and PS3.
