"Screen lamination" does not mean retina.
They have not been secret about going with a new anti-glare technology. It's unclear if this means matte, like in the old (and glorious) days when a night light didnt reflect out half your screen. Even if it's not matte, lamination on glass reduces glare significantly. As far as I know, Apple would be among the first to do an IPS display, laminated directly to the surface element, at the 27" size. [[edit: it's not Apple doing it, but one of their OEM builders, probably LG, but you never know]]
So... don't read into "lamination issues" any more than is warranted.
As far as redesign, the hardware specs (more standard cpu, ram, gpu, SSD standard for your $; USB standard; a couple of TB ports) are all pretty much a given. The 680M GPU is what I and many others are really after. The optical drive is take-it-or-leave-it. Personally, I wouldnt mind it, but its not a dealbreaker if its gone. A simple USB external CD-DVD burner can be bought for $15 and takes up almost no room in a drawer for the 99.9% of the time you're not using it.
Since I plan on mounting this bad boy to a reticulating or cantilever arm (wall mount to pull forward and to the side for use), I'll be happy with any weight reduction. In theory, the drop in nm processes for the cpu and going full ssd means less heat generated overall and SHOULD allow for less weight in heatsinks and maybe other parts. (quality heat sinks are usually copper and among the heaviest pieces in a computer)
I wouldnt mind retina, since that would mean they'd knock the price down for the non-retina displays and let the savvy among us get the discount and let the marketing-hypnotised drones take the hit to the wallet for the tech they could only appreciate (at actual viewing distance) if they sat with their nose on the screen.
And as far as looks go, lets face it - it doesn't look bad as is. It's practically all screen and tries to stay out of the way of the display. It might be more of an evolution, just slimming up the profile all around as they get more efficient with the design process and exploit the cooler hardware.
