I mean, not quite. There are a couple of things going on here - part of it is the character builder aspect, but that's not the whole thing.Also, aside from the monetization angle (which you could add through a third party app if you were so inclined) can't D&D Beyond or (heck, microsoft onedrive or even google sheets) do EVERYTHING they're planning on charging to do?
This just seems completely unnecessary except for the added buzzwords.
The article suggests that they're proposing a shared world where all of these characters exist and play happens in that shared world. So it at least sounds it's like a combination of Adventurer's League and D&D Beyond except you can sell your characters and also you can't make your own characters, you have to use a pre-gen. Which will have different elements of "rarity" around them in their stats and background and whatnot - so it's like D&D Beyond mixed with Adventurer's League with a bit of CCG thrown in maybe?
