CR did stream Fairy Tail. The deal they had let them keep the episodes for 30 days after that they went to Funi.
The hope is that CR's 30 day deal can carry over to the next season
Funimation licensed the first 48 episodes of Fairy Tail in early 2011, and it began in fall 2009. The 30 day limitation existed from the beginning and was unrelated to Funimation's later license.
Given that Funimation has now licensed the entire series, I fully expect them to grab the simulcast rights for any second series.
FT was always an odd bird on CR, not only due to the premium user only 30-day license, but also because it is one of the few (or only?) series that is available to a few other countries (France, Belgium, & Switzerland), but not the U.S. and Canada.
