Mearls has explicitly stated that Settlers of Catan and Monopoly are the models for D&D moving forwards: evergreen core rules, occasional themes releases.
Ayup.
I get why WotC would do this. I really do. But it's not the only way to proceed, and it's not predestined, and it's going to have consequences that a lot of people aren't expecting. That they probably won't even realize until a few years down the road, and then they'll either quit D&D or switch to a different game, and WotC won't blink an eye.
