Well, according to Castle's Tech Support, it doesn't look like the firmware update is going to be released this week. A few small issues popped up that they are working on fixing. He also said that it shouldn't be much longer. Sorry to get everyone's hopes up earlier, but I was merely passing on the info that they had given me over the phone.
Just got my v3. Very nice touch of Castle to ship out what appears to be brand new retail boxed units with the cables and such and not just a repaired unit.
