Right - Darkfall is being developed by Aventurine, who are a small indie type developer in Greece. They've been developing the game for sodding ages, beta was originally supposed to start about 4 years ago, and they have a history of not keeping to announced dates for stuff.
A lot of people thought the game was vaporware, until they actually sent out closed beta invites (although no one here got one). Beta reports were extremely controlled and limited. The latest I've heard is that they're going to do a very limited launch, presumably because they've underestimated interest or the amount of infrastructure required to host an mmo.
The impression I get is that they're quite competent programmers, but are severly lacking when it comes to hardware and infrastructure expertise.
Expect it when you see it on a shelf I'd say. And even then don't buy it until you've seen a few reviews.
