The below buyable/quested furniture will be added with Game Update 66 on April 30, 2013.

All of the below are sold on Mavla Zulexz (4324, -821, 423) in the Scarstone encampment in Cobalt Scar for 18g each. While the furniture is fully tradeable, it requires that you have at least obtained the adventure quest "The Lost Othmir" to unlock the ability to purchase it. Until I have time to actually wade through the entire adventuring line (after I finish all the preview stuff), I can't tell you if these buyables are also quest rewards or not, but it is my understanding that they are.

A Combine Commander's Gravestone	A Veteran Combine Gravestone	A Simple Combine Gravestone
A Combine Gravestone	Crustid Brain Coral	Diseased Brain Coral
Exploration Map Table of Wakening Lands	New Combine Freeport Standing Banner	New Combine Gorowyn Standing Banner
New Combine Kelethin Standing Banner	New Combine Neriak Standing Banner	New Combine New Halas Standing Banner
New Combine Qeynos Standing Banner	Scarstone Barrel	Scarstone Crate
Scarstone Defense	Tubular Coral Pod

If you are thinking that the Exploration Map Table of Wakening Lands looks a bit odd, it is because it isn't actually a table. What it is, is what is shown above - stuff to lay on top of the table of your choice.
