Those guys at kDnF have posted a new update on their test server message board, stating that they are too busy playing with their balls and as such do not know when the First server will be ready to be open to the public.
They also stated that they will post any news to the availability of the First server on the board as well, after playing with their balls.
The feedback board is also open, so if you got time to play with your balls, they encourage players to post some crap there once the first server is open for public testing, which is after playing with their balls.
