A BT spokesman said "These games are going to need to be chargeable, that's true. But they'll be far more affordable than today's competition. So today, to get the whole competition, you typically have to pay Sky £40 or so a month. The pricing is not being announced today, but I can say that this will be far more affordable than currently."
So it looks like BT sports is going to become more expensive than it's current £15.00 per month, but less than £40.00. I can't see SKY Sports decreasing in price. I can see BT Sports asking Virgin back round the table to renegotiate their deal come 2015. Of course we can only wait and see however it looks like football fans are are going to be paying out more than ever in 18 months time
