Thanks. Not an issue for me - I'm certain my Touch is not considered "newest".
As for why only Japan has the bug-fix: it seems pretty reasonable to me to roll them out in limited releases - especially if you're not going to do very exhaustive testing before the release! You might also choose to release to Japan first if there are specific bug-fixes for multi-byte character sets, or other regional issues.
