Segas Tekumi Yoshinaga, manden bag DS-spillet Project Rub, udtalte sig forleden om hans næste spilprojekt ved et event i Tokyo. Selvom han ikke gik i detaljer med projektet og slet ikke ville af- eller bekræfte om spillet var en decideret fortsættelse af Project Rub, så sagde han dog følgende:
"I am currently developing a title that kind of expands on the world of Project Rub. I create my games with the hope they will make people happy when they play it I can't talk about the details yet, but I'd like to keep creating these kinds of titles, which will leave something in the hearts of the players. The key point is communion between the hearts of people."
