The upcoming 30th Anniversary Leader Jetfire. Jet mode will be based on the G1 Toy and has the boosters. Yeah, looks like the Valkyrie. Robot mode will be based on the cartoon look. White and red colors, new mold. It'll have the cartoon face and a hybrid style face mask.
For now, please take this with a grain of salt.
EDIT: This came from a reliable source who's seen it.
And he's updated that Megatron will be a Tank in G1 Colours.
I for one, am stoked. With luck we'll see pics during Toy Fair on the 16th-19th.
