A job agent site in Japan named Job Engine posted late last month a job listing for a Project Planner for a Project Diva game on the PS Vita. The site in question has been consequently taken down due to the link being advertised on many other blogs. However, this shows that SEGA is planning on extending the Project Diva lineup to include the PS Vita, and hopefully, they get to use the touch capabilities, and the graphical capabilities of the Vita to its full extent to create a great game for everyone to play!
