The roster is here:

I knew I would love it anyway because Lizardmen, there is a notorious lack of heroes. No Gor-Rok, Chakax, Tiktaq'to, Oxyotl, etc. And yes, there aren't Troglodons (maybe because his rules were so bad they couldn't transfer it?), either hunting packs, or Rippers, or Swarms. Ark of Sotek is not here too. It smells like DLCs with a couple of FLCs. Which is fine, maybe we will get a subfaction, just like Orcs got Savage Orcs, this time focusing on Southlands, and/or just an expansion, including Troglodons and, I really wish, Cold One Skink Riders, and the Ark of Sotek.
Also, no Kroak, but that's fine, he shouldn't be out unless there is an inminent danger that no one else can do.
What I found funny is that only Basties can carry EotG, I wonder if Zlaaq will carry it (man, I love those Dinobots references).
And the live stream (careful with the chat, the amount of normies and mispelling is alarmingly dangerous):
Square bases and Henry painted hi Stegadon with the Lizardmen painting guide (which he haven't played yet. Trigger warning).
Also, don't think Kroq-Gar is the best fighter out there. He is probably between the Top Two. (I lol'd so hard).
However... better for you to judge it, but it seems that Saurus units will be rampage out of control if they hit ceratain health point (But they said that they will have a ton of HP and decent armour).
Skink seems to be ported perfectly, Kroxigors will be smarter.
There will be feral dinosaurs. Cheaper and harder to control, and will get more expensive as you upgrade them.
There is a brand new artifact for Basties: Revivification Crystal, and ever Lizardmen unit Cold Blood will heal them out of combat.
