So, I suspect that the Society would have a hard task in writing a new "Creation" book, regarding the overwhelming updated evidences.
My high school chemistry teacher was a bit of a lunatic and a also a creationist. He and I would have long, rambling discussions about the Bible and how evolution was false. Sadly, this was a public school in the United States and it's not uncommon.
However, at one point I parroted the line in the Creation book about the lack of fossil evidence for so-called missing-links. That was a step too far for even him. He corrected me and said there were hundreds of specimens and that he'd seen them with his own eyes. It was out-of-date information by the time it made it into print and the Watchtower conveniently never bothered to correct the record.
The passage of time has not made Creation-book-style rebuttals any easier. But I don't think that's the reason for not having any updated literature along these lines. It simply doesn't fit with the new paradigm. The WT today is focused on dumbing down the literature as much as possible while stressing obedience at every opportunity.
Pseudo-intellectualism is a relic of the past that then new batch of GB members have no interest in continuing. For all intents and purposes, literature in that style ceased to be published shortly after Fred Franz was laid to rest.
