I have found all of WOTC's 5e supplements to be disapointing and/or of no interest. The current releases just continue that trend.
Strixhaven: A magic school is something in which I would, normally, be interested. However, in addition to having no interest in MTG or MTG settings, the previews sold me off of this book hard. Time to track down Redhurst Academy (although I would just use 3e rather than convert it to 5e) or just run a Magic Academy in some other system (e.g. Cortex Plus, Pip System
Witchlight: Despite liking the idea of the Feywild and researching third party Fey products, I have no interest in adventures. I will, however, probably look for reviews of the Domains of Delight pdf that WOTC posted to Dungeon Master's Guild. It appears to be about the Feywild and creating one's own Domains of Delight. To bad, there is no print on demand option should I be interested.
Fizban's: A dedicated dragon book can be cool. However, like the 3e Dragonomicon, I will be giving this a pass. Based on a video overlook of the book, only Chapter 5 (and, maybe, Chapters 3 & 4) are of interest to me along with the Dragon Turtle, Sea Serpent in Chapter 6 (I can take or leave Draconians and the gem dragons). Granted, pagewise this is more than I found of interest in SCA, Xanathat's, and Tasha's combined, but it does not make the book a worthwhile enough purchase for me.
The Critical Role book, as with the other books, I have no interest.
