Auto Guide reports thats Lamborghini will be bringing a technology concept to the Paris Motor Show (This may be what the 83X is), but without the Jota.
They believe that all the teaser pictures we’ve seen so far have been of this technology concept, which will make extensive use of carbon fibre. The technology seen on this car will likely filter down to future Lamborghinis.
With the variety of rumours on this topic recently, all we can do is wait for the Paris Motor Show to see for ourselves.
