They never took of
Only a few years ago, BSH launched their new ovens over here in Europe, and with that, they launched several itterations of the microwave-oven combo.
The highest end one is WiFi connected, with moisture assitance, a 3-point roast thermometer, an auto-bake sensor and on top of that all it is self cleaning with self-clean safe guides/telescopic runners and baking trays. This TOL retails for about 1500€, the next lower in line without the steam assist and WiFi is only ~1000€.
