I think that there is some misunderstood here. The Unity staff can confirm that, but the point of the DOTS, as the name suggest, is using data-oriented approach. The current prefabs, for example, are object-oriented and they do not fit into DOTS. So yes, there will be new prsfabs for DOTS and they won't necessarily merge back into the old prefabs (and this is not bad news, as it will give a chance to Unity to re-structure the entire prefab workflow as needed without worrying about retro-compatibility).



Using MonoBehaviour is the standard way right now, and you can use the hybrid approach, but to take full advantage of the DOTS power you will need to leave behind a lot of things (like the object-oriented prefabs that we have right now).
