Just seen the Tactix & Epix lovechild - Tactic 7 AMOLED:

It's the new top of the range Tactix and even includes the AB Software, but comes in at a hefty AUD $2.5k. But it does have some whizz bang cool features, which may appear in the Fenix 8...?
I am sitting in the dark staring at my Fenix 2 with backlight on and pretend it is a Tactix 7 in redshift mode.
