If they want to go more premium, which seems to be their MO, then a RWD platform with an AWD option seems like a must in order to compete against other premium manufacturers, almost all of whom use RWD platforms and longitudinal engines. I think more inline sixes is a great thing, especially turbocharged. A poor man's JDM BMW, and no, I am not talking about the Supra.
