Looking at his github profile (shared in another post) he looks like an approachable fellow as well. It definitely would be interesting to see where Emacs goes, he mentioned he already had some ideas, hopefully we get to see and appreciate those new features that come up.
Just recently discussed on emacs-devel in the past few weeks: improved IDE features, concurrency, test-driven development, and guile-emacs. Big ideas for such an old code base.
