Well, let me get started...
1. Will, say, an 88mm gun be able to hit a B17 on the ground and destroy it?
2. Will vehicles be visible from the same distances as planes?
3. Will vehicles have to travel from the same points as planes? I.E. Fields? Or will there be "checkpoints" or towns where they leave from?
4. What range of vehicles can we expect?
5. What kinda guns are you giving my FlakPanzer?

6. Will there be any ground modeling? Will a truck or tank have trouble climbing a hill or mountain?
7. Will vehicles be manable by more than one person?
8. A little off topic but will we be able to man ack? If so, will each person get a limited number of rounds to fire from that ack?
9. Will we be able to carry drunks to a field in a truck?
10. Will there be roads for the vehicles to travel on? If so what kind of incentive would there be to stay on the road?
11. Will we ever have large artillery pieces?
12. If trains are implemented will they have ack cars?
13. Will vehicles have different loadouts like planes?
14. Will vehicles such as the FP be available at fields for defense or will there be a limit to them?
15. Will vehicles ever be damaged by bombs and such? (related to Q 14)
16. Will fields have defenses against vehicles such as minefields?
17. Bad question but what is the first vehicle planned? (tentative)
18. How many questions can I think of? Wait a minute...
Well, that IS all I can think of. Sorry if you've answered some of these already Pyro, just want to know some of the answers. Also, a long list, don't have to answer all of em.
