I doubt it will ever have a true manual trans, even in the hype-r, it will probably be a multi-mode dual cluch automatic with a manual, paddle shift option and then standard auto and then a "sport mode" auto.

you might get away with using a piggyback like the AEM FIC4 but I don't believe it can control direct injection... you'd have to add secondary injectors or eliminate the direct injection and convert it to more common port injection. The issue you have there is you'd have to swap the oem ecu back in and revert the motor back to its stock form for it to pass the OBD2 emissions test
