Having seen today an image from this weeks White Dwarf (if its fake it was really good).
FOC (Force Organisation Chart) are still here no percentage based forces like widely predicted, but you can forego the FOC and just take whatever you want. Sounds a bit wierd and can see things like riptides being spammed, but you get a bonus for sticking to the FOC what I saw didnt state bonuses but did state it was fully compliant with all current codexs.
Also a return of the psychic phase and strategy cards are being brought back in. More to follow soon hopefully.
