Also D&D may be having a massive surge in popularity, but this game has a huge appeal outside that, from Bioware fans to Witcher fans, to cRPG players to D&D players. And this will be one of the biggest and first fantasy RPGs to launch on a new generation of consoles so there's that audience too!
The most important thing is a fun and balanced single-player game based on 5E, not necessarily sticking to it for better or worse, but adapting it where needed to make a more engaging experience for everyone.
