Just a couple of quick thoughts:
1. regarding binoculars stowed in a case, that's not usually the case (no pun intended ) anymore. Since WWII (some, and nowadays just about all) military binoculars have been clad in protective rubber armour (example of three 1950's-1970's German ones) enabling the user to have them dangle around the neck without having to worry about them being knocked up. Generally speaking, military binos are built to be very sturdy.
2. fix focal length or zoom? variable focal length binoculars (zooms) are very uncommon amongst military field binoculars (and usually shunned by 'other professionals' such as birdwatchers) because a zoom design is more difficult to water/weatherproof and generally less sturdy. Apart from that, image sharpness usually suffers and for a zoom binocular of a given size to gather as much light as a fix focal one (usually 7x or 8x), it would have to be considerably larger, adding to bulk and becoming more unwieldly (same thing with photographic lenses or rifle scopes). Therefore I very much like the implementation in OFP/ArmA, in regards to a fixed focal length (while a zoom thingie fits the sci-fi theme of for example S.T.A.L.K.E.R). A better rangefinder reticle might be nice though.
Regarding the animations, as said before, I assume Arma 2 will feature generally more fluid animations and not ones like the current ones that are somewhat Hidden & Dangerous-esque. Perhaps we'll even have dipped headlights as opposed to only high beams?
