way too early to sell them now, 6N just started to take off.. my honest opinion is that 7N will still experience a Buyout in late 2016, but u don't have to wait that long.. once 6N is not that easily affordable for the masses anymore 7N will get into the spotlight and be where 6N is now.. and such triple 8 7N will be where triple 8 6N are now, giving a nice return
