Digital Games from XBOX 360

but on the faq on Call of duty ghosts website it says

When I upgrade from digital download for Xbox 360 to digital download for Xbox One, will my digital Xbox 360 game license be deactivated?

No, Xbox 360 game license will not be deactivated. Both game licenses will be retained.

I am really confused, does that only apply if you buy the game of the dashboard?

Also will it be available Nov 5th...?

but what about digital codes for xbox 360 games,i'm trying to buy the ninja gaiden 3 razor edge digital code from my seller.Like will that digital code work,is there some actual pal or ntsc codes for the xbox 360 console?

I have found this but Amazon does not write that in their description, they write the opposite

But what I found on another website was this

"Microsoft offers the Xbox 360 + Xbox One Digital Combo, a disc-less dual-license that provides the Xbox 360 digital version of Call of Duty: Ghosts, as well as the Xbox One digital version of Call of Duty: Ghosts – linked and unlocked via a user’s Xbox
Live gamertag. The Xbox 360 + Xbox One Digital Combo will be available at participating retailers for a suggested retail price of £64.99."

Q. When I upgrade from digital download for Xbox 360 to digital download for Xbox One, will my digital Xbox 360 game license be deactivated?

A. No, Xbox 360 game license will not be deactivated. Both game licenses will be retained.

This essentially means that should you buy the license, you will be buying the game for both consoles simultaneously. Sweet idea?

Xbox 360 games are not compatible with PC, so I'm sorry but they won't work.

it will work, if you bought the digital copy from the MS market place it will work not sure about any others:
