I really hope not...but if it is true all that means is you have to buy a nice handful to ensure your always covered. I had to do this with the Z Putt'r. It's my bread and butter but no longer being produced. I have 5 and add one about every 4 months from a surplus with clearwater disc golf store. I hope to have a minimum of 10 before they run out. But that's all you will be able to do. I am sure if this happens there will be a large stock of them still available. The ESP plastic is very nice as well. My current Wasp is an esp and it's been great.
