As I have search throughtout the item.era-go.com (Item Database) I have come up with some teasers that you might like. After Coop showing some features in the trailer such as, Hunting, See people Cutting Trees, and Treasure Hunting.
*Sorry for the "Horses?" thread ignore it for now lol*
Horses:
Their are about 4 types of horses, White, Black, Brown, Brown (Dark).
It cost $5000 Gralats. I'm not sure if they might raise the price.


Seen from this update photo you may or may not have seen in the background

Wooden Axe (Woodcutting Job):
Based on the trailer the Coop made, we saw people cutting a tree in the trailer. Also Calli has been seen in Gangster Zone in iEra testing out "Woody (NPC)" cutting out wood. Well now this is how much the item to cut trees worth. Again as I said I'm not sure if they might raise the price.

New Weapons? (Compound Bow):
If you have seen the trailer there is a guy shooting arrows to the sea. Take a look at this picture. Done? Now compare it. If you look closely on the description present_town


Hunter Knife (Non-EC)
Before you say "Whaaaaaaat" How is it possible? Well since you are pretty much hunting bears, boars, etc. You gotta kill an animing with something.

Puzzles? Weapons from Era! :
As seen from the trailer. There is like two buttons and the other guy grabbed it and suddenly warped to another room. It is also seen that he is holding an ACannonThis maybe the possible way to get the chests?

Pickaxe? :
Suddenly another perfect melee with $9999 and doesn't show the picture.
