just going to put this link here. The picture and discussion on the cheersandgears board will be enough to raise some eyebrows.

From that picture, everybody's just guessing.

they are definitely over analyzing it...to my knowledge nobody has seen the new STS...and i doubt Cadillac would unveil it in a picture with 5 other cars...but who knows...probably just two cts's...maybe they like even numbers...although that being the case they could of used an Escalade and an ESV...then again i dont know what im talking about either so..........
