Ok, I don't think Shade is LE, because a while ago Son_Risa posted pics of the color swatches from the MAC book they keep at her counter. I saved them on my comp for future reference, so I just checked the pics, and most of the products have triangles next to their names on the swatch sheet, but Shade Fluidliner has a square next to it, so I'm pretty sure that means its permanent!!!
Hope that helps!
