In the past, notably in the "Insight" book article on "Messiah" the WT have given the impression that the Bible says that the Jews were expecting the Messiah at this time for a particular reason. A careful reading of the texts they use shows no such thing.
The Jews were always, (and still do?), awaiting the Messiah.
I can find no scriptural example of where they used Daniel to work out that the Messiah was due at the time Jesus appeared, and nor any secular proof that 1st Century Jews were any more "expectant" than at any other time in history.
Perhaps the WT is becoming aware that their dodgy "scholarship" is easy to see through, and is being held up to derision on the Internet, perhaps, and it is a big perhaps, they are getting a little more careful about what they put in print.
