Zeitz (the new guy) is worth reserving judgment on. For one of my side gigs I did some basic research on him just two or three years ago. The track record is significant.
He took charge of Puma when he was young (30-ish) and the company was in trouble. It's now an international powerhouse and doing much better than the German economy more generally. He stayed with new ownership after Puma was acquired several years after his tenure began and reports suggest good work there as well.
For a generation or so the guy has preached sustainability and eco-sound production in large business and doing that in ways that don't contradict business efficiency. He was (if you believe the press) a big reason Harley is now doing the LiveWire.
He's only announced as a placeholder so far. No clarification on how long-term he'll hold the reins. Hell, there's no clarity on whether Harley's reins are worth holding for another generation; at least not without a major re-boot that would leave all of us old farts scratching our heads and wondering what the company and all its young whippersnapper new customers had become.
Hell, I wish just about any new guy luck and any company good fortune; both for its employees and its shareholders and its customers. So for a short trip or a longer ride good fortune to the new German and any vision / change that might lead the company forward such that it can once again find ways to even get out of its own way.
