Apologies if there is some repition here but I thought I'd collect together the photos I was able to get:

I heard that the weird glowing yellow guys around the archon's feet are mandrakes, not sure of there will be new model for them, wasn't on display.

I heard that the archon's cube doubles his strength if he can kill an independent character or monstrous creature. Archon has WS, BS & I 7 stats, but most of the rest are 3 S, T, W.

The incubi are quite cool, I like the way they hold their weapons in two hands in two different ways (lose the horns though). Didn't see their codex entry.
