I know I said I wasn’t going to post rumours any more but these are rumour confirmations so it doesn’t count…
This little lot was on Bell of Lost Souls.
Hullpoints: The previous rumors are true. Vehicles move to the new hullpoints system that will eventually kill them after receiving a number of critical chart rolls. Look for 3+ Hullpoints on most vehicles.
Allies are IN: As had been suspected, a new army chart will report the level of cooperation various armies can have. This will not allow cherrypicking of valuable units from another codex, but instead the ability to integrate a second FOC chart into you army from the selected ally. How deep you can develop this second tree (beyond the mandatory HQ and 2 troops) is determined by what level of cooperation the armies have on the chart.
Fortifications: The truth exceeds the mission based rumors. Look to find a new “Fortification Slot” on the FOC that all armies can access and use in standard army construction. Surprise, surprise, the common choices available happen to have existin Games Workshop kits already available.
Close Combat Weapon AP Values: This is true, and look for a full chart listing all the common CC Weapons in the game and where they land from AP1 all the way down to AP-
Hull points is an interesting idea and it’s good to see close combat weapons get a steroid shot. Although I can’t help but think that both these changes will benefit the forces of the Imperium more than most. But I guess we won’t have long to wait to find out…

Im looking forward with my chaos armies, i wonder what the chaos allied slots are like.
I imagine a little thin on the ground. Orks and probably Dark Eldar.
