Fenix has very good quality lights. I had this light and it is good, I just couldn't deal with the tint as i am used to neutral tints. It has a slightly bluish tint to it. As far as I know, there are no plans for an update on this light.
Another solid option for a similar light is the Fenix PD32 which i think people favor more than the 35tac.
I ended up giving my PD35tac to my dad and he loves it. For similar lights of good quality(not quite as good as fenix) and better emitter choices, i would recommend eagtac. Best of luck in your decision
