I don't follow GW news, but I still use their paints. Apparently, they are being overhauled:
I've already had to develop a new skin method after they ditched bronzed flesh - not a disaster as I prefer my new one, but was a pain for matching. They also changed graveyard earth i think, which I use buckets of. But my main concern is whether Devlan Mud will survive. They wouldn't change it... Would they?
Even more tempted to move to Vallejo, now.
