To shed some light on this, Chrome will be stopping its support for certain type of plugins in the near future. This should not cause any trouble accessing the game for anyone. While they'll no longer support plugins such as Adobe Flash, Chrome has its own integrated Pepper Flash which will continue existing and be updated and all that.
So in actuality all this means is that you won't be able to have two version of Flash on Chrome (their own Pepper Flash and the Adobe Flash plugin). It might do more good than damage as having both versions enabled has been known to cause trouble due to conflict between the two.
