Opera Voice (tenor in B major): "Il portafoglio è mobile!"However, this willingness to switch editions is apparently not the norm among those who play D&D, which is what WotC found out the hard way. Now they have determined that evergreen is what makes them more money in the short term and long term, while we certainly cannot predict the future, it is safe to say that they will follow the money.
It's more normal than you think. There have been some fairly large changes in editions for a lot of industry games out there: Der Schwarze Auge, Fate/Fudge, Warhammer, 7th Sea, etc.We should also note that most other TTRPGs don't go through drastic rule changes between editions—this is not the norm in the industry, and many players (like you said) are not a fan of the throw-the-baby-out-with-the-bathwater method of edition upheavel.
