Microsoft has posted Xbox One’s lineup on games on Xbox.com. Among the list is Crimson Dragon. Interestingly, Crimson Dragon isn’t listed as an Xbox One exclusive, but as game which will either be exclusive to the Xbox platform or will be released exclusively first on Xbox. Specifically, the words used are:
Titles in bold are Xbox platform exclusives or exclusively first on Xbox
What this means for Crimson Dragon remains to be seen. It at least doesn’t rule out an Xbox 360 or PC version of the game. The Xbox 360 can certainly be considered a part of the Xbox platform, so perhaps Crimson Dragon will still make it to the 360 after an initial Xbox One launch (the 360 version has not been officially cancelled). Perhaps we will see a version of the game on other Microsoft platforms at a later date, similar to the PC releases of Microsoft published Xbox games such as Halo, Gears of War, and Alan Wake.
