Land Rover can't afford to make a popular car/4x4. Since the destruction of the mass uk car industry (longbridge is going to be a housing estate with names like allegro drive etc) they must use their relatively small manufacturing capacity to make high price/profit vehicles like the RR and Evoques, they're flat out just satisfying that. A car type vehicle would just sell too well but need a new factory £bazillions.
I wouldn't object to a LR / Jag crossover again, seeing as they're the same company, with a Jag car. I had an x type which had 4 wheel drive developed off the back of the freelander system with ird and viscous coupling, it was awesome in the snow.
They deleted the viscous coupling after 3 years tho, just put a diff in it, too many warranty problems. Later x types could get stranded then if one wheel got on ice, trick was to dab brakes to get it moving. Very underrated car and not a Mondeo with a different body as popular lore would have you believe (they did share 18% of components but a lot of that was stuff like air con components, wiper motors, rear calipers etc, though the diesels used a whole mondeo front subframe and drivetrain and weren't 4wd).
That said LR have said there's new models coming so there you go.
