If you are referring to "The Official U.S. Casino Chip Price Guide" by Campiglia & Wells the current 3rd edition was published in 2005. It is doubtful that we will see a 4th edition for 2-3 yrs or more. The only fault I have with either the "Chip Guide or "TCR" is no supplements are released in between publications. Other than that they are the best reference books available. If I am wrong on this someone is sure to correct me.
