Ngee Khiong recently posted some scans - of note is this one that seems to show Skywarp with altered colour scheme - more G1 accurate.

It doesn't look like a bad scan (the rest of the colours are fine), but it may be a photoshop job.. (there's hints of the original purple in the car photos). I did like the purple of the first batch of photos, but black probably looks better - all i know is i just want it now!
