Looking at the video I see there is no GH. Also if you look there is a "VIP" on the screen. That suggests a subscription system for extra exp, drops & possibly daily 'prizes'. That is a move some other F2P games are doing to reduce the reliance on IM sales. Personally I feel that is a good move.
There also appears to be Class Advancement MPCs that suggests the class quests may be a thing of the past.
I have heard they did something with Rakhon, relocated some of the common dungeons, removed some and added others.
Here's a post from someone that did a little snooping around in it. Keep in mind that it is not all set in stone and can change as quickly as a client patch when you start the game.
