Welcome to Librarium Online!
Well, at last GW gives us a little info. I just got my new WD in the mail and here's what it lists on page 18 as upcoming releases.
Wood Elf Lord on Great Eagle.
Wood Elf Lord on Great Stag. (Yes, it's the model whose picture has been on the 'Net for a while now, the one where the stag looks rather like a beastman)
Wood Elf Lord with Two-Handed Weapons (I'm not sure why it says "weapons")
Wood Elf Lord with Bow
Wood Elf Army Standard Bearer (the female model that's had pics floating around, maybe?)
