Thanks to Josh for this bit of detective work. It appears that rsxbyacura.com has been registered by the Genex company. As you may know, Genex.com maintains for Acura the nsxbyacura.com and integrabyacura.com websites. With the release of the prototype pictures called RS-X and with the website being registered, we believe that the next generation Integra will be called the RSX.
We'll most likely have confirmation of this at the Detroit Auto Show in January. One of our editors will be there to take pictures so stay tuned. -Tuan
