I ended up purchasing "Codename: Blast Off", which details the early history of the relaunch of GI Joe in the early '80s.
The short story is: if anyone is at all interested in the history of the 3 3/4" line as told first hand from those who created it, this is the DVD for you. There's a lot of insight into the production, many cool Easter Eggs (Keep an closed eye on those serial numbers on the vehicles)... there are criticisms I can make for the production quality of the DVD, but overall, I consider it $25 worth spending.
If you guys are interested, I can do a more detailed review in a new thread.... let me know.
