As far as I know, the Note 2 isn't getting an official update to Lollipop. It's over 2 years at this point, and it received a good amount of major updates. You'll have to root and ROM if you want it
I'm fine with not getting an update. They tend to mess something up. Prime example was my POS Bionic--the last update it received brought back the dreaded whine in the headphone output. I ended up buying the Note 2 because of that problem, rather than wait the usual length of time between new phones. thanks, Moto...
