The Ark? The Nemesis? Teletran 1? The Code of Primus? Or will that be left behind from now on? I'm curious tis all. Any ideas?
At the writer lpanel they talked about how at one point in the script Prime and others in the Ark waiting for BB's signal and the Ark is hiding in Saturn's rings but it was dropped. They then suggested the possibility of the Ark being in a future movie.
Maybe the ark is somewhere crashed on earth and the Autobots from part 1 could find it. I seriously doubt that would happen, but it would be cool.
