Spied 2013 Acura RSX??

VTEC.net posted some images of what is supposedly the 2013 Acura sub-TSX. Some people are referring to it as the RSX sedan. But wait a minute, I thought the TSX was a "RSX sedan". Rumor has it that this future model is based off the Civic platform. But wait a minute times two! An Acura based off the Civic?? Isn't that just an Acura CSX?? My head hurts. My little brain is not powerful enough for Honda and Acura's ingenious ideas...
