The cut-outs are used for special effects, camera coverage and actor eye-lines and suggest that both characters enter the action at ground level in some form or fashion. The real question is since Shockwave's G1 alt mode was a Cybertronian gun and his appearances after that was a Cybertronian tank, what will his alt mode be now?

Nelson from MB.com has now posted the extended edition of his Transformers 3 Chicago set video. According to TFW2005, the differences is Rosie talking to Tyrese, Bay and company greeting the crowd, a look at the Ferrari 458 Italia & Mercedes-Benz E350 Autobots, a scene being shot, and a brief look at TF3 teaser poster.
As for more videos, the one after the extended MB.com video is a compilation video that shows of a Chicago transfan capturing a lot of new footage I have not seen before. The beginning shows the probable stunt double for Shia running down the street, jumping over and under cars. After that you get a look at them filming at Hotel 71, from office windows, and a slideshow of more photos. Thanks again to DJ Big for the link. The second shows Shia LaBeouf in Chicago meeting the fans, taking pictures and signing autographs. Thanks to Josh P. for the link.
