I would like to know when episode 66 and onward of Fairy Tail 2014 gets English dubbed.
According to Wikipedia Funimation will release Fairy Tail episode 2411 on September 6, 2016 as apart of Part 21 of the Home Media Release (Episode 240 - 252)
this is also confirmed on the Funimation Store
Fairy Tail - Part Twenty One
Blu-ray & DVD
Note that Funimation uses the weird US style of dates where it's MM/DD/YYYY and not DD/MM/YYYY so the date in the quote is indeed September 6th and not June 9th.
1: Fairy Tail 2014 series is Season 7 and Fairy Tail Zero according to Wikipedia and still retains the episode order. as such Fairy Tail 2014 episode 66 = 175 (last episode of Season 6) + 66 = 241
