The only thing I know is that Japan have the option of 30 of those 50 - nothing else has been announced to date. I somehow doubt that 30 private individuals in Japan will eventuate (such has the low uptake thus far for the NC1), which may give the UK and Australia etc. a slim chance of nabbing a car or two in RHD.
Sadly, I'm not in a position to register my interest for another Type S.
