@Welsh, I was thinking more about Wh3 pre-order and about different possibilities for it. In Wh1, there are two more placeholder factions. Kislev and Southern Realms, so technically, just technicallly if CA ever planned Wh3 pre-order to be retrospecively playable in all three games, maybe one of those will be pre-order bonus.
Firstly I depends how the Wh3 pre-order will work.
1)Like Norsca, which was Wh2 pre-order and is not playable in Vortex, only in Wh1 and ME....and ME2.0 (ME2.0 is new ME in Wh3, will be separated
) ......so this Norsca like preorder would be playable in Vortex, ME, ME2.0 but not in main Wh3 campaign
This would limit us to two possibilities
-Araby, which is well represented on both Vortex/ME in Wh2
-Southern Realms with token appearance on Vortex and good on ME
2)Due to Norsca ME launch problems limiting pre-order to be just for Wh3...(Wh3 main and ME2.0) as having faction solely for any ME campaign is ..well not for everyone. I think this culd be real possibility, as CA had major pain in the ass with Norsca...
This could lead to any faction,race...
-Kislev.....with strangely shaped campaign map even even others...or whatever
3)Very unlikely scenario, in which CA planns the Wh3 pre-order faction to be playable in all three games Wh1+Wh2 (or ME?) + Wh3 (or ME2.0)
-Kislev...is well in Wh1, is not in Vortex but is again well in ME...so it will be well in ME2.0 and we suspect it might be even in Wh3 main
-Southern Realms..is also well in Wh1, has token appearance in Vortex and again well represented in ME so even ME2.0
-Araby...is not in Wh1, while is well in both Vortex and ME...so even ME2..
Of course this whole speculation is big IF...
