Wondering the same thing. I was really hoping it would have the Retina HD (which is pretty much just better viewing angles, improved polarizer, and much higher contrast ratio) but there's no mention of it on the tech specs. I figured that if the contrast ratio/viewing angles/polarizer was improved they would've mentioned it on the product page like they did with the iPhones, but there's no sign of it anywhere.
I suppose the laminated display will make the screen seem closer to the surface and might help when you're using it in a glare-y environment, but I was really hoping for the improved contrast ratio. Shame, because the blacks on the iPad look washed out and gray compared to the deep blacks on my iPhone with the Retina HD.
