Namco Bandai have registered teh trademark Soul Calibur: Lost Swords in the United States. And that's really all the information we have on what we suspect is a new game. It could be that Namco Bandai want to lose the number for their next entry in the series or we could be for another handheld installment (like Soul Calibur: Broken Destiny) or a spin-off (like Soul Calibur Legends). Regardless it's good to see Namco Bandai keeping the fire burning as Soul Calibur has struggled a bit in recent years (at least as far as sales figures go).
