It doesn't define this as happening in the next OS, just as a iMessage update ."Later next year, we will be adding support for RCS Universal Profile, the standard as currently published by the GSM Association. We believe the RCS Universal Profile will offer a better interoperability experience when compared to SMS or MMS. This will work alongside iMessage, which will continue to be the best and most secure messaging experience for Apple users," said an Apple spokesperson.
also this was stated
IMHO it's worth doing this sooner to show DOJ/EU that this isn't an issue to examine.Apple offered no details on which iOS update might include RCS support. And it's unclear just how many generations of iPhone will support the communication standard.
