Here's a link to what they are currently working on at the CA (Company behind Total War):

Apparently they are in the development of the next part in the three parts series of TW: Warhammer, with no explanation to which races will be involved in the next game.
My guess would however be that Lizards could very easily be a part of this; here is why:
The first game saw the races of Orcs, Empire, Vampire Counts and Dwarves; all of which are based in the Old World. So far every DLC has also only been for races of this part of the world. Which obviously suggest that each game part, is based on some part of the Warhammer world; hence the fact that they can be combined into one game, when all are out.
Since we haven't seen the most iconic race of fantasy yet (High Elves), it would make sense that they would be the front characters of the next game; that is Ulthuan, as one part of the map. With HE comes Dark elves, very naturally, whom are placed in the New World, very conveniently also where the Lizards are native. DE are even one of the most famous raiders of loot in Lustria, when they aren't fighting there fellow elven kin.
With Lizards as the other good faction, my final prediction would be Skavens as the last faction of the next game. I don't think they need to be explained, but it would make for a nice combination of elite and hordes in the new game as well.
My only issue, is that I can't see how they could make a new game purely based on Ogres and Tomb Kings, so I might be wrong and the next game is only three factions.... hopefully Lizards is among them, no matter
