I've had ESPN/ESPN America since before when it was NASN.
As far as I am aware there will still be a channel called ESPN with BT Sport 1 & 2, at least for the time being. BT Sport have bought the UK channels of ESPN and also the rights they had so I think, I may be wrong, that they will still be showing US Sport on the ESPN channel.
What I am annoyed at, as a subscriber since the days of NASN is that (as a Sky Digital customer that doesn't have BT for broadband) that they expect me to also pay a £15 connection fee in addition to the subscription, so I've decided to cancel it, and my just subscribe to MLB.tv online seeing as I can now connect up with my smart TV. ESPN had already lost the ice hockey so the only thing I'd be missing would be college football and I don't watch too much of that anyway.
