I'd say that the relationship between BT and VM, on the TV front at least, is more cordial than their relationship with Sky and they appear to be open to working together.
With BT Sport there was no VM announcement until after the channels launched last year. What you may see is a similar event this time, with AMC Global launching exclusively on the BT platform at the end of August and maybe it appearing on Virgin a few days later as part of XL. Technically that would mean an exclusive launch for BT but carriage on VM within days.
And I'd expect AMC's top shows (Fear The Walking Dead, Rectify etc.) to be repeated extensively in the first week, so we may miss the first showing but not the first show (if you see what I mean).
