2018 A6 Upgraded or Not?
 

Thinking about swapping my 2012 A6 for a new one. Have read that 2018 model due in fall will be have major upgrade in technology. Spoke to dealer salesman who said that '18 will be essentially the same as '17 and new tech won't be out until the '19 model. Have not been able to find any clear info online. Anyone got the real scoop?

Thanks - Joel
