Spencer has noted that there is apparently interest in seeing Phantom Dust being re-imagined or some sort of a sequel being developed for the Xbox One platform. Phantom Dust was a called classic on the original Xbox. It is possible that a reboot should meet with much success.
One possibility is a Crimson Dragon RPG. At E3 back in June, Futatsugi commented to Joystick that he does have interest in developing one around Crimson Dragon. The best news is that Microsoft is talking to Futatsugi about developing something new and they are going to develop something new.
