Listed on a couple of Online-stores (including one which has been known to lists things that are just rumours, just to be first to get money from desperate fans), so until it is listed somewhere official, or we see a sample, I'm not yet listing this as confirmed.

Besides, I can't imagine that a toy as fragile as MP Starscream would be cast in translucent plastics. Yes, the redeco is said to be Ghost Starscream, done in see-through plastics. A toy that often breaks just by transforming it, will now become more of a display item, as I wouldn't even wanna risk transforming a transluscent one at all.

No idea if this will be a general release item, or a limited release like the Grimlock redeco.

I think it will look nice, but will be an expensive display piece - a gimmick that should be left for a smaller, cheaper version of Starscream.
