BF 2 is sure to keep the arcadish game-play the way it was, since that is what made the game so popular.

BF 2 will be more realistic in some degrees but the game-play won´t change much, which is a good thing. And example for the improved realism is that tanks-shells will no longer drop to the ground after 10 yards. Expect tanks to be more as in FH.

As for strafing, I´m not sure what you exactly mean. Because you can strafe in any FPS, including BF 1942...

Fatigue is probably the only good idea of yours. I think, if implented correctly, it could improve game-play a bit. Maybe the ability to sprint for short distances, but having to holster you weapon might add a lot. But I wouldn´t wan´t stamina to have direct affect on you accuracy or similar...

Some sort of hit effects might be cool, as seen in Far Cry or similar. Besides that, low health shouldn´t have much of an effect on a players character. Beeing stunned while shot at would suck, since every weapon would stun their opponent emidiatly, hence making him an easy kill...

Vehicles in BF are easy to drive already. I could hardly imagine how you could make it even simpler ! In BFV you are able to shoot from vehicles so I expect we will see that in BF 2 aswell. I agree that sometimes beeing stopped by a little bush can be anoying, yet this was due to the engine, which will be totaly recoded.
Planes in BF are simple to fly once you get used to them. Honestly, what do you expect ? They fly like X-Wings, just with slight gravity.
And if you can fly planes in BF, you can fly choppers in BFV. JO flight controls really blow. It feels just like riding a lift, not actually flying. The same applys for all vehicles in JO. That game just sucks so bad. They should fire their physics programmer...

Your last suggestion could actually work, if combined with a certain objective. For example if team A contols the radar station, their commander gets to call in Carpet Bombing every 10 min. However I wouldn´t recommend implenting such things otherwise...
