Infinity Ward's Mark Rubin has come out and officially stated that Call of Duty: Ghosts will run at 720p on the Xbox One. He also confirmed that the PlayStation 4 version will run at 1080p.
"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," Rubin said on Twitter. "Still on the road, but glad to see the great reception to [Call of Duty: Ghosts co-op mode] Extinction. Can't wait for next week's launch."

There you have it. An official confirmation to the rumor we saw about a week ago.

Xbone is 720p upscaled to 1080p at 60fps and the PS4 is 1080p native at 60fps for Ghosts. This news comes hot on the heels that Battlefield 4 will run at 720p on Xbone and 900p on PS4.
