In an interview conducted earlier this week, videogame trade publication GameDaily spoke with Namco Bandai’s Chief Producer, Daisuke Uchiyama regarding a number of subjects. Though the main focus of the discussion was Dragon Ball Z (another title which Uchiyama is producing), the creator did reveal that the Soulcalibur team was already working on a new title in the series:
“[Namco's development staff working on a future Dragon Ball Z title] would be the ideal scenario,” commented Uchiyama. “But a new Tekken  and Soulcalibur are already in the works, so it is [currently] not possible.”
The news of another Soulcalibur is nothing new. In a conversation with IGN held in April of 2005 Namco officials had already revealed plans to work on a sequel:
“Namco is definitely planning to develop the Soulcalibur series on the next-generation platforms,” Namco told IGN. “However, when we started development for SCIII, the specs for the next-generation platforms were not set, and there were no dev kits, which ultimately lead us to [Soulcalibur III's] development on the PS2.”
Flash forward to 14 months later and in the aftermath of Uchiyama’s statements to GameDaily, Namco isn’t as forthcoming with official information. “The Soulcalibur team has been looking into new projects after the completion of Soulcalibur III on the PS2,” commented a Namco Bandai representative to IGN. But the next project for that team has not yet been confirmed. We will keep you posted.”
So what does this all mean? It all depends on how you like your news. If you like it “official style,” then of course, nothing has been announced yet. If you prefer the more traditional “somebody who would know what’s up told us in a conversation” method, however, then you have two separate sources from Namco Bandai telling two separate publications in a 14-month span that the game is on its way. Take from that what you will.
