I taped the trailer and watched it several times, but this detail wasn't clear enough for me to see until I downloaded it.
There is a shot of the Republic Gunships banking towards the ground which comes right after Sio Bibbles dialogue. In that shot, the Gunship closest to the camera is clearly carrying Ki Adi Mundi. He's standing there with Mace and several other Jedi, although Ki Adi is the easiest to recognize.
I wonder though. Are any of the Jedi piloting those Gunships? Or are they somply riding them into battle?
At any rate, we know how the Jedi get down to the surface now.
