In a response to a fan question on Twitter, Phil Spencer has confirmed that Blue Dragon is currently being worked on for Xbox One backwards compatibility.
Originally released in 2007, Blue Dragon is a Xbox 360 exclusive JRPG developed by Mistwalker (who went on to create Lost Odyssey) and Artoon.
Spencer had previously expressed his desire to get Blue Dragon onto the console a year ago. He also stated that he was “not allowed to say,” but said yes anyway.
@Jfranklin4160 I’m not allowed to say but yes.
