They wouldn't need the Pontiac Solaris car if they were just going to do a flashback with Jazz on Cybertron. He wouldn't have had that vehicle form yet. And given the set is supposed to be a scene apparently located in China, it couldn't be a flashback from the first movie.

 

Remember the misinformation campaign that the Bay folks said they'd be doing? It's not so tough to drive a Pontiac around Bethlehem and get us fans confused, drooling, and p i s s e d all at the same time.

Wait... Could there be a connection between Bethlehem and someone's ressurection? hmmm......

 

Well I'm willing to wait and see what happens.
I personally think Jazz's death was a total waste.
The characters in the movie didn't really care, so the entire scene was pointless and unnecessary.

 

am i the only one who thinks Jazz should've stayed dead????

probably..
