While I am happy about the focus still being on adventures and settings (Ravenloft + Dark Sun), this other book gives me a sense of deja-vu... we're now getting into "revision rehash" territory pretty much like it happened more than 20 years ago with 3.5 and "splatbooks" which included a little new material but mostly just "revised" versions of older stuff that didn't really need a revision, but now need an adaptation to stuff that was also unnecessarily changed in 2024 (such as subclass starting levels). Players now "need" to buy another book to choose subclasses or spells that were already there. Some truly new options will be there for sure, but given the recent level of creativity by WotC you can bet they will mostly be about extra damage, extra healing, or advantage. Don't be fooled by the "high magic" tag, it's just a marketing ploy, there won't be any high magic module or system, "high" here just means that most of of the book is about magic, but it is the same kind as always.
