Supposed Earth Vech Mode for Megatron in DOTM

Have any of you heard about Megatron getting a new earth truck vech. mode in the third Transformer movie? Found these pictures on a ebay listing for a supposed prototype Voyager Class DOTM Megatron truck. It's not the actual colors as what will be released. If this is true...I think its sweet and finally have Megatron take on a earth vech mode!

If memory serves...Megatron has been the following various toy modes:
1) A dragons
2) A dinosaurs
3) various guns
4) alligator
5) tanks
6) cars
7) space ships
airplane (machine wars)
9) Rocket launcher vech. (Botcon-like Red Alert from Armada)

**Think of any other vech or animal modes, I'm forgetting?

**Anyway here's the pics of DOTM Megatron:

I heard of this rumor. I don't believe it to be true.
Any new molds Megs get should be a conversion into GALVATRON.
I would say this figure will be either Onslaught, Motormaster or Octane.
But you know how Bay works, he'll probably name it Predaking. LOL
