Well, we already know what the functions are. It's a DNA20 in a nice case. There's quite a few DNA20 mods out and publicly available, and even more home made.
As far as I know they haven't shown a working version of the end cap/button that lets it convert to a mech. So right now we have a DNA20 module which has an evic style threading. So while that is nice, the converting to a mech part, pertaining to a set of tubes they are making, is what makes it truly a must buy for a lot of people.
