Imo it will have an impact, as now Blizzard doesn't need to provide anymore results for non-videogame industry shareholders (Vivendi = a lot of things apart from videogames). Some of these were certainly having a big enough share to have a significant influence on global products direction, and this direction was not necessarly priorizing the videogames department. The punchline "can now focus more on its videogames" takes a lot of sense.
