As i undestand it the dual channel is not somthing we can expect to see this year, the GT2S and later this year Gt7S is what we can expect from jokiin.
When it comes to the dual channel setup there have been new hardware released and so forth to consider for jokiin, and not forgetting all the input from the potential users that will have to be implemented.
My guess is that around august Jokiin will start to Work real hard on the dual cam setup, but it will be a "long march" as it will need new tooles to be made and so forth.
I am praying for dual separate ( very small ) cams 1080p / 30 FPS each - DVR with room for a ssd for storage, and a USB plug to transfer a little footage off device and onto a thumbdrive.
