Despite the increased focus on music, attendance for the 2015 X Games dropped by about 30K from 2014. Although the 2014 attendance was the highest in 10 years. ESPN has been struggling to increase interest in the X Games which is why they had the well publicized nationwide search for a new venue. IMO it's still supported well enough to continue through the last two years of their COTA deal, but after that, who knows?
