I could be wrong, but I think I read somewhere (maybe on TheDigitalBits or something) that they are shooting for April.
Don't quote me on that though.
That's what trekcore has said as well. I'm actually looking for when the series will be available for pre-order, since last week I got a giftcard from Amazon and kind of want to use it. I guess it doesn't matter too much since I'm using it for TNG, but I would have thought a date for pre-orders would be coming soon.
