Lordpack - Eltharion vs Grom - I think this is pretty much nailed on to be coming. Great for the Greenskins, i hope they add some forest goblin units beyond the spider riders for sneaky stuff (maybe some skirmishers?), bolt thrower.... not sure what else? I've no idea what High Elf units are likely beyond the White Lion chariot. Please not sky cutters, they are ridiculous. Imrik might come along, could be FLC, although maybe FLC might come along in the form of boosts to old races as per the Brets this time around.
Wood Elves - (My biggest wish, i'll admit) Sisters of Twilight, Araloth, melee & swiftshiver shard variants of gladeriders, melee warhawk riders, ROR (ethereal Dryads, maybe warhawk riders on great eagles?)
Brets - I realise this is probably unlikely now, but i'd have liked them to get a little love. Bertrand the brigand as a hero and his peasant bowmen as a ROR, maybe a ROR pegasus or Hippogriph knights... they need a little help.
Dwarves - Josef Bugman (second biggest wish, Dwarves not having any ranged special characters is weird), Burlock Dammison (Master engineer), Ranged regular Lord option, Daemon Slayer hero (deals magical damage?). Something that deals magical missiles would fit as well, maybe some rune laden cannons or thunderers as an additional ROR (although Dwarf ROR has aged better than others, and already has more options)
Beastmen - Ghorgon is obviously popular, and while i'm no expert on the faction they feel a little neglected
Empire - Boris, a couple of Ulric units, knights of the white wolf, Teutogen guard (third biggest wish)
Norsca - I don't really know enough about options for extra lords or heroes for them. The roster is still pretty great tbh.
