Heard from a sales manager at a dealership that this color is on hold because of problems producing it. Didn't say what the specifics were, but he thought once the problems were worked out, the color would be available in the future. Before that, I had read on the net that the white diamond tricoat is so popular that GMC decided to keep offering for now. And then sometime in the near future, would bring out the color. I too, am interested in seeing it on the Acadia. If anyone else has more info on this, please post.
