Something I kinda noticed a few days ago,
Funimation had released a survey and listed several possible shows in the list. In both lists in both questions, there was an option mark for Anohana. If any of you guys want to see Anohana having a U.S. release, it's a good time to fill that survey and vote for Anohana. And besides, since it's Funimation we're talking about, it will help increase the chances for an English dub for this show.
Mind you, however, that it won't be a 100% guarantee that Anohana will be released by Funimation, since surveys are often subjected to manipulation. However, it's at least better than nothing.
