Why Is The 4.2.2 Update for The htc One yet to come?? or should I root it??

I have been waiting for the 4.2.2 update for the htc one for the past 3 weeks and htc is not even giving a clue about the possible release date...

i really want to try out 4.2.2. by friends who are owners of s4 think it's funny not to have quick settings, and having to go into settings for almost any change i need to make.

so does anyone have an idea about when the update is coming??

or should i root my phone??

i am new to android and i am really scared of screwing it up... is the process safe and easy??

and again, even in the case i root, which rom should i use??

please help, this is a newbie....
