That better be a new vehicle. I don't understand why they even made arma 3, arma 2 became popular only because of dayz, I never really heard of arma 2 before dayz.
I'm a big Arma fan. Played Operation Flashpoint (of which the Arma games are the spiritual successors), Arma 1, and Arma 2. As mil-sims, they are top notch, especially when you start adding some of the realism mods. However, I'm not sure I'll end up buying Arma 3, as I don't like the Steam requirement. (Plus I tend to use Linux exclusively, and it won't be on Linux either.) Despite that, they are fantastic sims, and I'm glad the series is still going. [EDIT] Never played Day-Z btw.
Despite being an alpha arma 3 is excellent, better than Arma 2 atm. The mods, think of the mods! Some backwards compatability [quite a lot truth be told], new tactical pace key, adjusting various stance key, can actually swim this time, snakes, physx, sea swell and other things and its not even finished yet! Added a carrier + F18 mods as you can see from below. Shame steam doesn't have smaller screenshots.
