I'm overall happy. There's a few glaring omissions theme-wise, but they seem backwards compatible enough for the time being. I'll be looking forward to a reworked Inquisitive Rogue (please just call it Detective) with all the cool new Rogue stuff.
I think we'll get a splatbook "Tasha Presents" that will have the Artificer, all the updated spells and items from Tasha's and Xanathars, and 4 or 5 subclasses per class, mostly from Tasha and Xanathar, and also the newer subclasses from Ravenloft, Fizban's, Bigby's, and Dragonlance, and maybe a couple new ones.
It'll synthesize and mostly replace Xanathars and Tashas just like MP:MOTM did with MToF and VGM.
