I think I’ll chime in here to explain a little.
As stated in the video, the development of both clash of clans and clash royale will not be affected by this.
Each “cell” inside Supercell is a small team of people that works as its own little business (To help make sense of this).
You also heard that two of these new games are being made in Supercell Shanghai.
So from us, don’t worry! The Royale team are still here to make features and improvements to the game.
