Thoughts on ArcheAge? (Game being published by Trion)

So this game literally came out of nowhere. XLgames developed it and Trion is publishing this in North America. Russia and Korea already have this game and it's been in Korea for about 2 years. It is currently in closed alpha for translations but it will be f2p with a sub option. From what I've seen this will bring some new things to MMOs. I'm really looking forward to the sandbox elements and the huge open world including a huge sea.

Some quick links if you don't know what the game is yet, there is a lot of info that isn't stated though.
