Correct, the WTS has many versions for the 50th Jubilee but always only in regards to the WTS organization and its existence and future. The WTS has quietly dropped the 7,000 year creative day by the wayside since 1987, revising any mentions of it after that to thousands of years. There was a trip up at one book study where some jws were using an older version of the study book, but the conductor only baptized 3 years before this study had a newer book and had never heard of the 7,000 creative day. So he called on a brother who said it was 7,000 years long but the conductor's book said thousands of years and corrected the older brother. My husband had to explain the previous interpretation before the conductor's baptism. The next midweek meeting, it was announced that members should get the newer copy of the book so everyone would be on the same page.
1987, last mention of 7,000 year creative day

Second, a study of the fulfillment of Bible prophecy and of our location in the stream of time strongly indicate that each of the creative days (Genesis, chapter 1) is 7,000 years long. It is understood that Christ’s reign of a thousand years will bring to a close God’s 7,000-year ‘rest day,’ the last ‘day’ of the creative week. (Revelation 20:6; Genesis 2:2, 3) Based on this reasoning, the entire creative week would be 49,000 years long.

How long, then, were the creative days? The Bible does not say; however, the wording of Genesis chapters 1 and 2 indicates that considerable lengths of time were involved.

The fact is, the Bible reveals that the creative “days,” or ages, encompass thousands of years.
