looking hard at the Performante myself, but could be they come out with the rear wheel steer this year?

Maybe with the facelift? It is my understanding that this year (next MY), there will be only a switch to engines with particulate filter (EU only?).

There was some debate earlier at the time of the Performante's introduction why rear wheel steering was included as the Aventador S is now offered with that system.  Lamborghini's reply was that with ALA and the car's short wheelbase, rear wheel steering added nothing in terms of performance.  That could always change but such an update seems almost unwarranted.
