Not really. I never honestly expected those to be available for streaming. It's very possible that the streaming rights for the specials and the movies are a separate deal from the streaming rights for the 200 TV episodes. I don't know how familiar you are with these kinds of business deals, but they are often very precise in terms of the language used and what's available vs. what isn't available.
There could be a number of different explanations, but I personally think that while Viz has distribution rights for the Sailor Moon anime (both of them, actually), they might not have streaming rights for the movies and Hulu -- I think part of this might have something to do with the fact that the movies are currently available for free streaming on Amazon.co.jp Prime. Just an idea. Generally if something is streaming on Amazon Prime (even a country or region's specific version of Amazon Prime), it won't be available for streaming on other stream sites because they're basically industry rivals.
Anime movies are typically not streamed on most US streaming sites so I wouldn't expect them to stream the movies either. Hulu doesn't have any of the Inuyasha or Naruto movies streaming either and only a few random Naruto and Bleach movies are on Netflix. As for the specials, Viz probably wants to save them as extras for the home video releases. If you want a digital copy of the R movie, you can buy a streaming version on YouTube. This ANN Answerman article goes into more depth as to why you don't see more anime movies in general on streaming sites. http://www.animenewsnetwork.com/answerm ... 21/.106702
