Namco Bandai gaffer, Hideo Teramoto, revealed that Cellius was developing the Vita-bound racer in an interview with Gamasutra, and gave a bit of background on the studio.
Ken Kutaragi who was running SCE at the time was in talks with Shukuo Ishikawa, the head of development at NBGI. They got to talking about how itd be neat to create a company, and it sort of went from there, he said.
Cellius got its start with the Cell processor architecture; the concept was to be an outfit that researched ways to use this technology to create neat things. So its not exactly pure research; its more about finding ways to expand the things that can be done with the PlayStation family.
Cellius is unlikely to become a full-time development studio however.
This Ridge project is in itself a sort of experiment to see what sort of Ridge game Cellius can come up with; its a very different development atmosphere from when I was working on Ridge Racer in 2006. So if we do continue making games, I think well still remain different from normal game companies.
We just hope the game's ready in time for launch. Can you imagine a new PlayStation system launch without a Ridge Racer game?
