My belief on why the Z28 nameplate wasn't used because they are waiting until the camaro switches platforms to the alpha(I believe that's the new chassis name) and becomes smaller. From what I understand, that's only like 3 years off, and the Z28 would launch as a smaller,lighter,agile car that everyone associates with the heritage that the Z28 nameplate stands for. If this is in fact the plan by GM, it's some great marketing because the camaro will continue to get a refresh and stay "new" in consumers eyes.(Introduced in 09, top of the line car in 12, whole line refresh in ~14, and the long awaited Z28 a year after)
