We still don't know if and when Samsung plans to deliver a similar update to international users, but it's probably a safe bet, since it will reduce further liability from consumer injury. Similarly, it's unclear if Samsung will make the update mandatory to Note 7 users in South Korea. Again, I would be surprised if it does. Samsung plans to start issuing new Note 7 models with updated batteries during the week of September 19th.
The Galaxy Note 7 launch has pretty much been a disaster for Samsung, with dozens of reports about phones exploding and injuring users. Ironically, the phone was also one of Samsung's most well-reviewed devices. The company is now working with the US government on an official recall in America, following a note from the Consumer Product Safety Commission which urged users not to use the Galaxy Note 7. For now, Samsung suggests that Note 7 owners don't charge or turn on their phones.
A battery limit isn't the most high-tech fix, and it's unclear if that's enough to actually avoid explosion issues entirely. But Samsung can't afford to be dogged by continued stories of its flagship phones hurting users.
