Being bored and looking around the interwebs, I stumbled across some more new things that may or may not be coming to DW in the future, All of these are confirmed to be in Dragon Lands, so they SHOULD make it to us eventually...
Armor Forge - You can craft armor in the Forge. Armor increases your dragons' attack and defense. Get your dragon a good suit of armor and you're halfway to victory!
Magic Lab ?? - increase warehouse capacity to 200 essences. (don't know if it's one additional upgrade or 2 (or 3?...)
SPOILER ALERT!
Just so everyone knows, this is all unreleased, do not put on the main wiki, forum thread only material here. :-)
