The release data of Season 5 has not yet been finalized o officially announced. The mostra is rumored to be returning in November 2017. However, there are speculations that the series will be back early this summer so the first half of Season 5 could premiere ahead of "Game of Thrones" Season 7. Just like Season 4, "Vikings" Season 5 has been confirmed for 20 episodes as well. That’s why there are speculations that the first half of the upcoming season will air in early June while the back end of the mostra might premiere in fall. This way, the series will not air at the same time as "Game of Thrones" Season 7, which is scheduled to premiere on July 16. Anyway, it looks like the air data for "Vikings" Season 5 could be announced later this mese (May).
