At this time we have only one decent view of the USS Kelvin. By baxart at 2008-10-22 I've been looking at this image and I think I've about got it figured out. I don't think the Kelvin has over/under nacelles. I think what we're seeing at the top of the image is the secondary hull's deflector dish. Notice it's blue/white which is consistent with TOS movie-era designs which it looks like the design team is sticking with. Also notice that the blue area is turned like an eye looking at the right side of the image. Why would a nacelle look like that? Below the saucer we can see a yellow/orange glow which would be consistent with TOS warp nacelles. Also note the black fin shape within the yellow/orange, I think that is one of the rotating fins we saw within the nacelle cap in the trailer. We also see what may be a nacelle cowling, also consistent with what we saw in the trailer. So these observations lead to to think the Kelvin may look something like this: By baxart at 2008-10-22 I pieced this together with Vance's toolkit: www.pixelsagas.com/gallery/viewgallery.php?album=5 and let the debate begin.
