I agree with Ken... I don't want to see them rushed either so it is worth the wait. And I am sure that being a new father is also taking up quite a bit of time too... can't blame him for that.
However, he has already finished videos A, B, C, E, & F. As far as the rest, here is a quote from a recent email that is sent to the Kickstarter Sponsors:
"Episodes D, G and H should be rolled out by mid August, and Episodes I, J, K and L follow in a more regular manner after that (as will be the rest)."
The videos so far have been great, but I will admit, I am looking forward to having the whole series on disc and in HD!
Also, I am not sure if even the completed videos have been made public yet...
