We already have a situation in which WotC produces stuff only available on Beyond (most of it free, as far as I know). That is unlikely to change and will probably increase as time goes on. We also are seeing bundles which are meant to draw people into the Beyond ecosystem, as well as FOMO-powered early access for subscribers.And I'm just trying to understand why WotC doing digital stuff matters if they also print the books.
The degree to which WotC shifts their efforts toward digital is a question of economics, but also of user preferences and technology. They can't sell you AI powered generation tools in print, for example.
There was a time when everyone assumed Netflix would always mail you DVDs.
