He must've predicted that a Jaguar Vision car would actually happen. Although it looks so different to what he thought it may be, from these sketches he saw. It is labeled as a coupe, so hopefully there will be a convertible version. Beyond that, don't expect any racing versions though, I think this'll remain in Gr. X. And even if they remove the article or host an embargo of leaked stuff, we already know this kind of secret they've been hiding.
