This led me to a
press release from August 26, 1996 in which DIC announces they've renewed broadcast rights in Canada through 1998, will start airing the show in Australia and New Zealand, and that they are still hoping to produce more episodes. (Obviously, as we all know, that TBS deal fell through.) Irwin Toys is also announced as the new master toy licensee, as is a deal with Croner-Tyco to produce Sailor Moon toys in Australia. (As far as I know, Australia didn't get any locally produced merchandise? Any Australian Moonies here who can comment on that?)
I also found
this interview between SOS and Roland Parliament from March 1996 where Roland says DIC was planning to dub an additional
40 episodes for "season 2," which would have brought them up to episode 112 (Super Sailor Moon's reveal/debut). Roland also mentions that Kaleidoscope Entertainment (the dub's distributor in Canada) was getting greedy and demanding a bigger portion of the profits, which was also complicating matters.
So basically from all this we can determine that DIC wanted to dub at least part way into S back in 1996, but the botched handling of the show's US syndication run (largely thanks to Bandai's marketing team) prevented that from happening. They needed to move the show to cable and neared a deal with TBS and Cartoon Network to produce 26 to 40 more episodes, but that didn't end up happening. It wasn't until the following year that Irwin was able to finance the dub of just the final 17 episodes of R.
It sucks that they weren't able to dub those episodes when they wanted to. We probably would have gotten all of S and SuperS with at least most if not all of the original cast and dub score. :\
(And now I'm imagining what it would have been like had Sailor Moon aired on MTV

)
