They're not really even in the discussion when it comes to being real replacements for DSLRs. Their sensor size is significantly smaller than even a crop frame dslr/mirrorless camera, and roughly a quarter of the size of a full frame camera. This smaller sensor size means they're not going to be used at the prosumer or pro level, and that in turn means a limited selection of high end lenses, etc.
