According to a statement issued earlier today on the Darkfall forums, the Non Disclosure Agreement for the game's beta has been lifted. Tasos Flambouras addressed this issue and others in a letter to the game's community.

As of the time of this posting the NDA is officially lifted. In the next couple of days the Darfkall pre-orders will open up and stay up until right before Darkfall’s launch on February 25th or until they are sold out. This is how the pre-order will work:

The pre-order consists of the Darkfall client digital download along with a month of play starting on February 25th. The full cost for this is 42 Euro. This amount WILL NOT be charged during the pre-order. What will be charged is an initial 2.52 Euro non-refundable payment to activate the process. The remainder (39.48) of the pre-release price will be billed on release, February 25th. You’ll be free to cancel the purchase any time before the additional charge goes in on February the 25th.
