So its 2002-2005 and the original xbox has a few games hitting 720p with the official Microsoft Advanced AV pack, games such as 25 to life, Amped 2, crash kart nitro, MVP Base ball 2004, MX unleshed, NBA2K3, Soul caliber 2, Tony Hawks pro skater 4, X-men legends, aswell as various others are outputing in 720p.
In 2008 onwards an few xbox 360 games run in 1080p native like Sega tennis, Rock star table tennis, Rage and a few others,
So why in 2014 is 1080p not the absolute basic standard for the xbox-one? Call of duty Ghosts on xboxone is closer in terms of resolution to the xbox360 than it is to PS4. I believe COD Ghosts runs at 640p on XBOX-360, 720p on XBOX-ONE then a MASSIVE jump upto 1080p on PLAYSTATION 4..
