Should it be a sequel to PSU way in the future, or a home version with all of PSP2's content and then some, or a revision of PSO with a megaton of new content? Maybe a mix? Or just something completely new using the best of both PSU and PSO? Or maybe it's Phantasy Star V with an online mode (possibly MMO or using the same content as offline but expanding like PSU, only more integrated). Definitely needs to be done with next-gen graphics.
