Upon its reveal, many thought that Marvel's Blade could be an Xbox exclusive. The title is being developed by Bethesda subsidiary Arkane Lyon after Microsoft's acquisition of Bethesda's owner, ZeniMax Media. This would certainly be a way for Microsoft to counter Insomniac Games' PlayStation-exclusive Marvel titles, Marvel's Spider-Man and Marvel's Wolverine. Despite this, there seems to be some speculation surrounding the matter.
