1) 6th ed boxset is set to be Eldar Vs CSMs, as they will be the among the first 6th ed codexes.
2) Eldar will be first, then Tau or CSMs
3) Force org in 6th is undergoing a fairly interesting change. Slots will be as they are, but you can sacrifice 2 FOC slots to gain an extra one somewhere else. you can drop 2 fasts and get an extra heavy. Or a heavy and a fast and get an elite. Only thing you cant get is extra HQs i think. ~He later states this appears to be a one time thing, (you can't trade in 4 slots to gain 2 new ones of your choice).
Interessant de pouvoir sacrifier et de rajouter un slot dans ta force, dépendamment tu style d'armée que tu veux jouer!
