yeh i've just had another look.
As far as i know it was/will be free to play used to say it on the old website and a quick google search says it was advertised as being free to play - now after looking through the new website there's no mention of it being F2P anymore but that doesn't mean it won't be as a few areas don't seem to be completed yet. might pop the question on their forums.
edit : looks like it is still F2P no specifics though i'm assuming WOT style F2P
