There is actually a third way to bound the age of the universe. And that is to say that it must be older than the oldest known stars. In particular, older than https://en.wikipedia.org/wiki/HD_140283 https://en.wikipedia.org/wiki/HD_140283. This star is (barely) compatible with the Plank readings. It is nowhere near a fit with the new figures. So while a lot of science has to be done to reconcile the methodologies, I'm betting that the universe doesn't wind up being a billion years younger than we thought.
