The special to air in October is not TDA. It is a continuation of TDI - thus the pictures of the voice actors do not represent the characters coming back for second season.
Also - almost ALL the question that have been asked in the past month have already been answered. You just need to read the blog. We're not ignoring you, we just don't have time to answer the same questions over and over again.
The show is made in Toronto.
...and no word on the DVD. Believe me, you'll know if we are putting out a DVD set.
