you know if there's any space combat it'll be an arcade shooter through and through
From the people who brought you planet scanning, hacking, turret sequences and ping to scan/outrun the reapers that's a pretty scary thought. Unless they take it seriously it would probably suck.
The ship should be a tactical asset through and through: artillery runs, supply drops, space missions, even in-ship missions, etc. In an ideal world in-ship command would complement the game perfectly, but they probably think that action through menus is boring compared to straight up action.
Not sure if they'll go down that path though. I think there will be a lot of vehicle stuff, and Frostbite certainly handles vehicles very well. Maybe they'll put in some upper atmosphere stuff.
Well, that is a given considering they've teased a vehicle already.
For the space stuff they probably won't, but space sims are having a big renaissance, and if Bioware is guilty of something it is taking concepts from other popular games in order to lure in that "expanded audience", so I wouldn't put it past them to incorporate more of those elements.
