I do not think so.
If people are looking for a turboed off-roader, they have the option of the Forester. If they want an on-road turbo hatch, they have the WRX hatchback.
It would be pretty awesome with the powertrain from the 2014 XT, but I really do not see that happening.
Maybe since it appears they plan to discontinue the hatchback WRX for the 2015 MY there could be a market for a turbo Crosstrek, but I don't know.
Either way, I would not buy it. I think the Forester is a better package than the Crosstrek.
