The word is that you will be able to redeem until you run out, at Regent anyway. Things can change but this is the intent right now. If they cannot "redeem" the gold points the normal way (not been able to do that for about 3 months already) they will give you Future Cruise credit of like value. They may offer some enhanced redemptions to get rid of them faster too, I would anticipate that.
So it will be a thing of the past eventually but any points you have I believe you will be able to use.
