If you don't know by now, the Xbox One will be Backwards Compatible some time next year. Not sure what the process nowadays is for games to become BC, but we should push for ACVD and ACFA (as well as its DLC) to be made available on the One when the emulation software comes out!
I don't have a Twitter, but if someone could tweet Namco/Bandai and Fromsoftware to see where they stand on the issue, please do it! Because, according to someone who watched the conference, it is really up to the developers/publishers to decide whether or not they want a game to be made available for emulation.
