Cheers for that, Jellico.The retooled chest does make it look much better.
It's only the back rise of the cockpit that forms the top of G1 Blitzwing's chest. Most of his cockpit actually sits on his back.
Although bear in mind that Generations Blitzwing was exclusively designed to be Blitzwing rather than being co-designed to be Blitzwing and Megatron. A similar argument could exist for CW G1 Megatron as that toy was concurrently developed to be Armada Megatron as well.
