I'd say it's a reasonable assumption that the brakes will be more reasonably sized to fit in production-spec wheels. I think I read somewhere that it's going to come with 245/45-18 tires on 18" wheels, but I'm not sure.

As for the appearance of the thing, I think for whatever reason the Acura press photos make it look even more bland than it really is. These pics from the NY auto show make it look a bit more expensive.

In that last one you can see an almost mini-Bangle effect to the tail lamps and trunk lid.

And it still needs a single-bar grille.
