At minium all PHB classes, subclasses, races, and subraces will be in, I feel certain of that.
I think some of VGTM races will be in like Aasimar, Goliaths, maybe, Tabaxi, Yuan Ti Purebloods, ect
Genasai might be in, but I hope the subraces get rebalanced.
Tortles I think will be reserved for a charity DLC like the original Tortle Package was.
Gith I feel fairly certain will be in, because of the Mindflayers.
I read one interview where it hinted at that will be more then just PHB.
All classes are likely in except Artificer and Psion, which don't have finished TTRPG releases yet, they are still in development. Subclasses might be more limited, most PHB will be in, a few might be too mechanically difficult. Some of XGTE subclasses could be in, like Divine Soul Sorcerer and Hexblade Warlock (both extremely popular). Good chance SCAG subclasses are in as they are FR setting specific (Purple Dragon Knight Fighter, Undying Patron Warlock, Storm Magic Sorcerer, Path of the Sun Soul Monk, Oath of the Crown Paladin, Arcane Domain Cleric, Bladesinger Wizard).
