From the rumors I have heard, they will replace the Pt Crusier with a vehicle based off of the platform that the Sebring/Avenger, Caliber/Compass/Patroit is on. It will probably share the same powertrain as teh Sebring/Avenger. It is better for the Pt Crusier to go out of production since there is really no room to change the styling and keep the styling cues without messing it up. Once you do retro correctly one time, it is difficult to get it right a second time.
