According to industry paper Automotive News, Porsche has confirmed the American event will host the unveiling of its new entry-level coupe.
The new Cayman will enter as a hardtop version of the topless Boxster, as did its predecessor. Little separates the two beneath the skin, including a new longer wheelbase, a wider track and shorter overhangs at each end.
Expect the 2012 Boxster's 198kW 2.7 litre and 235kW 3.4 litre engines to feature, along with the usual Cayman and Cayman S grades.
In Boxster form, the engines deliver 0-100km/h times of 5.7 seconds for the regular model, and 5.0 seconds flat for the S.
Watch for an Australian debut in late 2012 or early 2013.
