So guys let me talk before you bring the pitchforks and the torches.
If we go with the information from the AMA and the way CA had done there DLC's than we can come to this conclusion.
First let's look at WH1 DLC's. The main DLC were the WE, BM, FLC Bretonnia and Norsca. WE and BM have brought there own mini-campaign wich were not well liked so CA dismissed this idea for WH2. They had 2 LL at the beginning (BM gets one free with WE) and then came Norsca with 2 LL as an pre-order. So from this we can conclude that in WH1 DLC races get 2 LL.
In WH2 the race DLC were TK and VP with each 4 LL. So we the player will expect 4 LL for the pre-order race pack.
Second the pre-order must fit in the campaign from the game before. So in WH1 Norsca was not a problem. But let's look at WH2. The main candidate would be Southern Realms (DoW) or Kislev (to a lesser). Where would they fit in the map?
If we go with 4 LL for the pre-order race, where would you put them in Vortex. And that is the important factor, the new race must be fully playable in Vortex, because that's what WH2 core campaign is. In ME it would be no problem but in Vortex i don't see 4 new LL and a new race.
Then we must look at WH3 core races. We don't know what races we will get but we all know that Chaos Dwarfs, Ogre Kingdom and Demons of Chaos will come. In WH1 and WH2 we got 4 core races at the beginning and WH3 needs a "good" race to counter the chaos and destruction factions. I think here would fit Kislev. So now we have 4 core races. If we look then at the DLC races we all expect at least 2 race packs, because that's what we got in every game. there lies the next problem. We don't have enough races left if we get an pre-order race for 2 new races. In my opinion the DLC races will be Cathay and Southern Realm (DoW).
The next point is the AMA. CA said that they would like to bring all WH1 races to WH2 standard. That would include the WE, the BM and Norsca. The WoC i think get there overhaul with WH3. That's 3 races that would then need an overhaul in WH2. Norsca personally i think don't need a big overhaul. I think that they function well enough. But they could need an new LL. They also said that there will be 2 more LP to come. That was before the new LP was announced, so we must assume that we only get 1 more LP.
And then we look at the last LP for WH2. I think we can all agree that it looks like CA will bring all WH2 core races to 6 LL. LM are done and with the new DLC the HE are also done. This leaves the SK and DE with each 1 LL. Also it looks like CA want's to bring all core races from WH1 into Vortex.
So all this brings me to the following conclusion. The next LP will finish the WH2 core races to 6 LL and brings one WH1 core race into the Vortex campaign.
My bet here is on Skaven (Throt) vs Dwarfs (Thorek) with FLC Dark Elves (Rakarth). My reasons here are that Clan moulder is prominent in the game today and is one of the last great Skaven clans missing. The Dawi would make sense as an nemesis. Also Thorek would fit good in ME now. Rakarth would make sense, because we already got the Master Beastmaster and he would be the LL.
That would then leave only the VC missing in Vortex for the WH1 core races. Here i think CA could make an FLC (maybe Everchosen event) I hope for Neferata, because she is already mentioned in the game today.
That then would leave the BM/WE and Norsca missing. And here i see the pre-order. A second WE&BM&Norsca DLC with overhaul for all three races. (more for BM and WE) As this is then a replacement for an race pack we should expect 4 LL. I hope here for 2 WE LL (Twilight sister and Drycha), 1 BM LL (Taurox) and 1 Norsca LL(Egil Styrbjorn). For units i think BM need the most. WE and Norsca could get maybe one new Lord and Hero and some new units. BM need a lot more units then the other 2 factions. For FLC in this i'm torn. From a faction perspective it would make sense to include the WoC (Valkia the Bloody) but this would only make sense if we get a first look in the new Chaos mechanic, wich i think will come in WH3. Maybe the FLC will be the missing VC LL.
So that's my thoughts on why we won't get an pre-order race. I know that's this is an unpopular opinion but in my opinion it's the most realistic one. What are you thinking on this? And please leave the torches and pitchforks at home. ^^
