This is mainly incorrect. The reason it is not here yet is because Honda perceives it will end up doing more harm than good for brand image and/or they're waiting for RSX sales to dip considerably.
Keep in mind Japanese gas is overated...their 100octate=our 92octane, for instance. As far as I know, the G4 ITR requires the same gas as the RSX-S.
