Just a few thoughts:
1. The show car is sitting on absolutely ginormous wheels. Even if the production car rolls out on standard 18 inches, it'll look quite a lot different.
2. Where does this fit into the Nissan range? Is it more 4x4 than a Qashqai but less than an X Trail?
3. If it turns out to simply be a kind of 4x4 coupe crossover, then I'd back it to be stacked a dozen deep at my local car supermarket by this time next year - the market reaction to the X6 shows, I think, that you can push the crossover thing too far.
4. But hey, kudos to Nissan for trying something potentially barking in the middle of a recession.
