Which new youth subculture will define the decade?

Emo and scene seem to be dying but I've noticed two other subcultures are appearing: brootal kids and indie kids. Brootal kids dress like scene kids only darker and they listen to deathcore, grindcore and metalcore instead of typical scene music. They tend to have a "tough" attitude. Indie kids have emo hair but dress with more vintage stuff like fedoras and t-shirts over vests. They still wear skinny jeans but they don't wear a lot of black. They tend to listen to indie music and their attitude is a bit pretentious and snotty, sort of "more alternative than thou." They think of themselves as intellectuals and artists. Which group do you think will define the '10s?
