" launching exclusively with the DSG twin-clutch auto (and a manual to follow)"
That would be true if we were talking about US models, here in Canada we will be getting both the auto and the manual right from the get go.
As much as I would like to think I'd go for the wagon with it's extra sleeperness and cargo capacity, I'd more than likely stick with the hatch back simply because it will be quite a few $$ less. IF VW decided to bring this over it will be a couple of thousand for the extra wagon space but also more because it will more than likely only be offered with a DSG, plus there'd be the possibility that they'd only offer one version that is fully loaded with tech package. So I would guess this Golf R Sportwagon, if it comes to Canada, will be starting around the $45,000 area.
