Recruit-A-Friend revamp?

So I’ve recruited a friend and heard earlier they’re going to revamp the recruit a friend again for patch 10.0.7 with new rewards. So if I’ve already recruited my friend and they’ve paid for 12 months of game time will I still get the rewards from this current reward tier or will it roll over and give the rewards for the new re-vamped version if the rework hits before their 12 months is done??

Since this question is not realm-specific, it would probably be better to ask this in the CS forum.
