Yup, I had the same thought!
Odds are there will be a few around in 20 years, then herd get's thinned early on, I think if it makes it to the 10 year mark, with routine work it should last. I've got an 8 or 9 year old duet that is still doing well, picked it up last year cheap because it needed a new pump. it became my daily driver, and I've given it a lot of use. I'll give this one a few more weeks of use and odds are I'll list the older one on CL.
