Make the manuals for SvC and SS0 dual language. The Japanese and English carts are released simultaneously anyways, so it won't take longer. So just make a bigger book. Or include both in one cart run.
That way you don't need to have an "English" cart run. People can read their manuals, as they claim they want to do, but no one has to suffer the pains of English cart overstock.
