Subaru WRX STI S209 teased for the USA

Subaru is getting ready to launch a track-ready WRX STI in the USA, in the form of the S209. At the moment, the only preview for the car is a video published by Subaru America, dubbed From Japan with Love.  It shows a heavily camouflaged WRX STI hammering around Virginia International Raceway, suggesting whatever is getting ready for release will be meaningfully different to the stock STI.
