Mods are not coming to Console or Mobile any time soon, the reason being that the owners of the platforms (Microsoft, Sony, Google, Apple etc) require all apps/games to be reviewed and tested before they are run on their platform. Some are more strict than others - even updates must be tested this way. This means that in order for you to get your mod on the platform, ReLogic/505 Games/DR Studios would have to submit the mod's code for review by each company, which is not feasible for a huge number of reasons.
Eventually, all platforms that have hardware powerful enough to run it will reach the same level of content as PC, yes.
