Well the CEO of WotC has said in multiple interviews in recent years that he wants to make D&D games across the full range of different types of videogames so that there is something for every D&D fan. In that spirit, I would hope WotC doesn't just have Larian be their sole developer for D&D RPGs, and that other studios with different visions for what would be a good D&D game also get to make D&D games so that those of us for whom this game is not what we want can also have D&D games to enjoy.
I believe there are 4 games in production right now as we speak. 2 have been announced. Dark Alliance and BG3 are the only two announced at the moment.
In a December 2018 interview he said something like 10 or 12 games over the next five years. But that includes mobile-only games.
My dream come true would be if they let Obsidian do a Neverwinter Nights 3 (with no change in the combat system).
And I would totally buy and play the new Dark Alliance if not for the fact that it cannot realistically be played single-player.
