Infinity Ward executive producer Mark Rubin has taken to Twitter to confirm the next-gen versions of their Call of Duty: Ghosts titles, revealing resolutions of 1080p upscaled from 720p for Xbox One and native 1080p for PlayStation 4.

The confirmation comes as recent rumours were swirling around the Internet for both Call of Duty: Ghosts and Battlefield 4, putting the Xbox One at a lower resolution than its PlayStation 4 competitor. The tweet in full:

Hey, been on the road last couple weeks so haven’t had a chance to update, but wanted to confirm that for Xbox One we’re 1080p upscaled from 720p. And, we’re native 1080p on PS4. We optimized each console to hit 60 FPS and the game looks great on both. Still on the road, but glad to see the great reception to Extinction. Can’t wait for next week's launch.

The confirmation of rumours is definitely a blow to Microsoft's next-gen efforts, something they've been battling the public eye with after their recent DRM fiasco earlier this year. There is solace though in the fact that both consoles will be running at 60 frames per second, a much needed change from the current generation.

In related Call of Duty: Ghosts news the new perk system has been revealed in detail thanks to a new blog post on the official website (thanks VG247). Eager fans can expect 35 individual perks available at their digital fingertips, each one "weighted with a point value of 1 through 5," meaning the higher valued the more it will cost to unlock.

Loadouts will have a pool of 8 points to spend on Perks, up to a total of 12 depending on your loadout choices. Points are earned through multiplayer play and with points won through the game’s new Squads mode. There are seven perk tress, all of which you can find in detail over here.
