the jaggies probably aren't from a low native resolution but from aliasing. I'm pretty sure that the NR is 720p but I could absolutely be wrong. i'm sure that somebody will figure it out sometime this week.

I found a head to head from eurogamer that said this:
For Black Ops, there have been changes. To the PS3 version at least. The Xbox 360 version remains the same (our measurement comes in at 1040x608 with 2x MSAA) but it appears to be the case that the PS3 game has been reduced to 960x544, again with 2x MSAA.
