Appears no slipcover was released in US for Vikings bluray season 5 part 1 but it was released in UK with a slipcover. I just got it from Amazon UK and although the slip and the cover art both list this as a region B release the 3 discs are region ABC. Also, Fox did not release American Horror Story season 7 on bluray at all in the US, but it is available in UK on bluray with a slipcover and once again the discs are region-free despite the packaging stating otherwise.
