My main worry will be as I've always said:
BUGS, SHIV was full of them to the point of, to me, being unplayable, I can live with most stuff but if I see ships crossing over land, aircraft flying into hills, seeing through men, bridge crew appearing & disappearing, views to rear compartment (type II) yielding a white screen, problems crossing International Date Line, empty eye sockets, wrong spoken orders to speed selection, well you get the idea!!
Introducing new stuff into the game usually also introduces new bugs! saying this though it does seem that the devs are doing a lot more to producing a higher quality game, a lot more time (to March) has been spent on this game than SH4, and since it uses the same engine, the extra time hopefully will be spent on beta tests and bug fixes, most other stuff, like realism can be fixed with mods!
