Old news really, they haven't really updated any news on anything except for that trailer 'supposedly' about game play, which they've had running around on the web for years. Seeing how it's made by NCsoft Korea, chances of it being F2P is very slim.
That's like asking if Aion is going to be F2P.
IMO I find Korean game developers way too ambitious for their own games, that they overlook their shortcomings when realizing that their game isn't that fun.
