wrangler wont be changed for sure,fiat dont wanna mess up the heart of jeep.but in 2013 or 2014,next generation cherokee,big chances to get changed,not 明年tho.
And jeep will make extra small suv like panda.
patroit,compass will be based on fiat group offering in 2012.liberty will be replaced by fiat midsize.Since the all new cherokee just came out,i think we will see what happen in 5 years.
