Probably not, as they are changing the base file structure for the game.
BSAs are compressed archives of assets that are loaded when you play the game. So, all the graphices, textures, meshes, NPC and Mob databases, gear and consumables etc are in these BSAs. These BSAs are being changed so that the entire mix does not have to be replaced to patch say one item.
Note, they may not call them BSA in this game, but the concept is the same.
