Based on information we do have access to, that seems extraordinarily unlikely. For example, Wildemount is the 15th-ranked D&D title on Amazon. That's not a straight sales-volume ranking, but it's a fair bet Wildemount hasn't "rivaled" Xanathar's or Tasha's, let alone the core rulebooks.I can't remember where the data was, but Wildemount was apparently so successful that it rivaled sales of the core rule books...
I like CR. I really like the people involved. I'd be just peachy if Exandria completely displaced FR as an Anniversary Edition default setting. The cartoon looks awesome and I hope it becomes a massive hit. But I also think there's something of a bubble effect in some of the statements that are made about its current reach.
