Unreleased G2 Jungle Attack Starscream?

{mosimage} A new auction has appeared on eBay, claiming to be for an unreleased G2 Jungle Attack Starscream, similar to the Desert Attack Ramjet that we have seen artwork for. The seller says that it is a hand-painted prototype made in-house at Hasbro as a proposal piece. Obviously, the proposal never passed. The same seller has a carded G2 Groove and has had unreleased G2 toys and artwork in the past, all of which lends credence to this current auction.

You can see the auction here and discuss it here . Thanks to Spark for the heads up.
