There appear to be references to journeys to India. This may alter dialogue with Buddhism completely, not to mention Hinduism. And there may be further controversial material about marriage, much in the news now days.
When I first read the Doherty's book JNGNM, my conclusion was that only if Q was discovered, then his Case could be questioned (and I would be again historicist), given the clear difficulties shown by Doherty in harmonizing Q with Paul (remember that Richard Carrier denies Q).
If Q did exist, it's impossible to ignore the pure and simple possibility that a historical Jesus said these sayings.
This is my reaction when I have listened the notice this afternoon.
And which is your first reaction?
