Well,this is sad,because this device is highly known and a great quality device. I think it deserves to get android L at least,and for future updates we cant rely on Cyanogenmod,because currently do not have a high support. I dont know who this guy Ethan Chen is,but i know that dhacker is a great dev,and his support was better. I'm 99.9% shure that he would port L and future updates if he was an offical maintainer.
So in conclusion,we just need barebone android L image and the majority of us will be satisfied.
