I suppose we don't know until the final game is out. I've been a bigger BF3 person over COD in the current gen cycle which had both games at similar resolutions. But COD had 60 frames per sec whereas BF3 had better livelier graphics with 30 fps.
However, for next gen version, if BF4 is 720p (or sub 1080p) while COD Ghosts runs at full 1080p (I'm guessing this is native and not upscale). Regardless of how much livelier environmental destruction (or levolution) that BF4 has, the difference in resolution from 720p to 1080p is huge. I'll likely concede that COD Ghosts at 1080p is going to look much better.
Of course, we don't know the final specs until the games are released. (On a side note, as a PS4 pre-order customer, I blame Xbox1 if PS4 BF4 is 720p on release.....)
