I don't Know where to post this... But..
Investigating in Acura.com and Honda.Co.Jp

Acura RL = Honda Legend
Acura TL = Honda Accord Euro Type R
Acura NSX = Honda NSX/HSC
Acura RSX = Honda Integra

So theres no such thing about kissing the Acura Integra goodbye and then bring up the RSX, It's Americas little change... Japan is still with the Integra and the NSX. No such RSX or HSC up there.
Although haven't even seen the TSX.... and the RDX is up there too, Along with the MDX.
