I'll take 1080p/30 if it means there is going to be unreal visuals during gameplay.
If you want unreal visuals, then you are gaming on the wrong devices. You must enter the PC zone......
Unless Halo 5 uses the cloud to enhance , (while I assume not, as I never heard of it), I cannot see how it can compete with UC4 in terms of visuals at when it is 60fps. MP no question, must be 60fps.
MS mentioned in a twitter last year that Halo 5 was going to be 1080p. So at 1080p and 60fps...and based on how awesome Halo 4 looked, Halo 5 could indeed be a graphics victor.
