Well if history is consistent with Acura, they tend to put out "radical" sketches of their concept cars, they state that "the production vehicle will look very much like this concept", but then the actual car that comes out for sale is a VERY tame version of the concept.
Remember the CL-X concept car that hit the auto shows just before the original 2.3CL? That car looked pretty sweet, with sharply raked glass and sheetmetal. However, what actually came out was a shortened Accord coupe with a funky alien-eye back end.
Honda issued some sketches for the TL-X too. Not too bad-looking, but what actually came out was the 3.2TL, another typical Honda, slab-sided with a few sheetmetal bevels here and there, with a generic front and rear view.
So I would take the RS-X drawings with a grain of big salt. Basically, the production car will have the acura 5-point grill, but of course those radical upswept body lines (side view) will not make it.
