Take this as a rumor for now but it seems that in some parts of the world, like Russia, the Nexus S will come with a Super Clear LCD instead of a Super AMOLED display. If that's true, it shouldn't be much a big deal, because as Mobile Review has shown, a Super Clear LCD display is about as high quality as a Super AMOLED display, although it may consume a bit more power overall.
What I'm slightly worried about is that those Nexus S owners won't get the phones with the S curveture in the display, since there's no way they can curve an LCD like that. I doubt many will consider it a huge drawback, but nonetheless it's something that Super AMOLED Nexus S owners will have that Super Clear LCD Nexus S owners won't.
