Over at 40k Warzone they have the Wood Elf armybook in hand, and have pictures for proof. Here you can see some of the details as they discuss what is in the armybook rather extensively.
They are doing a full look at the new armybook, so here is a link to 40k Warzones main page if you want to take a look. So far they have talked about the new Wood Elf Rules and Magic Items.
