Another upcoming MMO from NCSoft with the exception of Blade and Soul. It looks just as good as Blade and Soul but the game engine is a heavy modded version of the CryEngine (That's right, Far Cry 1's engine.)
Game features:
In the game of Aion you have the ability to fly across the big world of Aion.
NCSoft confirmed that a US Release in Fall 2009 but they didn't give anymore details. Korea and China already began their open beta a while back.
If you're wondering, you have to buy the game then pay a monthly fee.
I've seen a trailer of Aion last year in a video game store, but I wrote it off as never gunna happen. Good to see that I was wrong. I wanna play a guy with 2h sword or fly around and hit stuff with big white wings.
If pvp can be something like the first trailer in OP's post I'd be giddy.
