FFA Full loot PvP Sandbox MMOs

Discussion about these types of games. Currently there aren't any good ones out there, as far as I know. I know there is DFUW, but the playerbase is just a bit too small for a sandbox game. I tried Mortal Online a few weeks ago, but it still feels just too clumsy and there are still way too many bugs around. For me, Darkfall 1 has been the best FFA sandbox so far, the launch was just amazing (even tho there still were problems, I know.)

So, are there any upcoming games with these settings? I've been keeping on eye on Gloria Victis, and the game actually just got steam greenlighted. It's gonna be medieval based, low-fantasy FFA sandbox MMO, dunno about full loot yet. But yea, it will take atleast 1-2 years before the game comes out. Any other games out there?

Did you look into ArcheAge?
Don't know if it completely fulfills your prerequisites but check it out.

An impressive preview site, which really makes one want to play the game. :D
Best enjoyed with audio available and a good bandwith. <3
