Some original Xbox games will be coming to Xbox One later this year, via backward compatibility. At E3, Phil Spencer from Microsoft announced that backward compatibility will be supported for some games, and that original Xbox games “will look better and play better across the Xbox One family.”
Panzer Dragoon Orta has not been confirmed. However this is definitely a step in the direction of Panzer Dragoon Orta on Xbox One becoming a reality.
Albert Penello from Microsoft also confirmed that original Xbox discs and digital purchases will carry over, so if support for Panzer Dragoon Orta is added at some point you won’t necessarily have to re-purchase the game to play it on Xbox One.
