this discussion has been coming around regularly for the last decade or so
Honestly, there have been a lot of great new DNA oriented Panerais besides the classics you mentioned over the last decade, I was fortunate enough to pick one up myself recently, the IMO incomparable 662, which only came out a year ago.
I agree that Panerai is offering more and more non-DNA watches, and is obviously moving into new areas of horology that have nothing at all to do with their history. But so far, they're still also providing a lot of stuff for the historically minded enthusiast to enjoy too.
So jumped the shark? Nah. Changing? Definitely.
