Here's some more confirmation of Samsung's plans for updating the Galaxy S4, S3, and the Note to Android 4.3 – French carrier SFR has released a roadmap with information about their devices’ upcoming updates, and it states that the Galaxy S4 will receive the update in October, followed by the Galaxy S3 and Note II sometime between November and December.
Samsung had initially said that updates for all three devices will start from October, but it isn't surprising that the Galaxy S4 will be given first preference. As always, carriers in the U.S. will take additional time to roll out the updates, though if Samsung Canada is to be believed, all three devices should be on the latest version of Android (well, latest for now, by then Android 4.4 ‘KitKat' will likely be out) before this eventful year ends, regardless of region and carrier.
In terms of features, Android 4.3 will add numerous new software features from the Galaxy S4 to the Galaxy S3 and Note II, while enabling compatibility with the Galaxy Gear for all three (though the S4 is already partly compatible).
