There has not been an announcement of "true" oneway rewards via email or any other scheme. There has been discussion of permitting the bookings online without requiring the return segment but that they would still be at the full price. I haven't seen any follow-up on that. And CO has made a number of announcements about the scheme for next year and adding one-way rewards in wasn't one of them. I don't really expect it to happen anytime soon.
