After taking a look at the video it also seems the down tube is a different shape and where the tt and the seat down tube meet is also different. As noted before the curve of the tt seems to be changed as well.

Also where the shifter and brake cables enter the frame in the front are different on this new model, on the current modes the cables enter the frame behind where the downtube and headtube meet.

Nice find of the pics and video. :)
