https://peginc.com/gamechanger-for-the-new-fantasy-companion-for-savage-worlds-is-live/I watched the livestream and it's going to be entirely different than the Savage Worlds Pathfinder and Core rules. Basically it's going to be a huge supplement to both. It's setting neutral, and completely Toolkit in design. It will cover magic from 11 different subgenres, including a ton of material that boosts standard D&D/Pathfinder style play, including more utilitarian powers (effectively mining the stuff not covered in Pathfinder), as well as other magical systems and setting conventions. They specifically used Game of Thrones, Harry Potter, Warhammer and a few a others as examples.
There will be expanded rules for Strongholds, PC race creation, rules for deep setting intrigue, magic items, and more.
They also said while it's not made specifically for Savage Pathfinder (or any other setting) it will certainly act as an Advanced Players Guide for Savage Pathfinder as well as greatly fleshing out the Fantasy genre mechanics for the Core rules.
