Exist a sore need for better DBs and is due the action is there. My only gripe is that most are focused in the MOST niches of the scenarios of the MOST exotics of the deployments (the kind that worry about stuff like multi-master across continents). The RDBMS need more fundamental improvements at the core (like for example, start supporting algebraic types!).
