I believe in this case FoxPro had a release date, but through field testing they learned there were still issues so they continue to push it back. At least that's my understanding on the 360. I'm not 100% sure what the issues are with the 48, but assuming something similar. I thought I saw the 48 available through allpredatorcalls.com at one time, but looking yesterday it says "out of stock". They don't even list the 360. What I think is interesting about that is if you look on the FoxPro website, they show the 360, but not the 48.....
