Will we see duplicate entries in D&D Beyond for the different versions of the monsters and races in the book? That sounds like it would be an untenable approach, but then technically people who own the original books would get "free" content without having to pay for the new one. It was a little more straightforward with, say, the Bladesinger since Wizards officially declared the changes errata and updated all new printings of the Sword Coast Adventurer's Guide to include that new version. It doesn't look like they're going to do that with the Player's Handbook, Monster Manual, Volo's, Theros, Ravnica, etc.
