I am so uncontrollably hyped for this.

I just got invited to the Beta lol, like 2 weeks too late since I was already playing it...

Is the game reasonably balanced? Can ground and air forces attack each other well?

It's fairly balanced, but the missle launchers and flak guns have an advantage over warhawks. It's possible to destroy them as a warhawk, but they can take you out much faster if they see you (unless you're good with the TOW missles). However, while the missle launchers and flak guns have unlimited ammo, they have to reload and that takes enough time for a warhawk to get a quick shot in (missle launchers reload after each launch, flak guns get 50 shells but you can reload them at any time). 

Those things are why I prefer dogfight only servers because you can concentrate more on fighting. 

Lair isnt pre rendered the gameplay looks amazing, and uncharted's game play looks better than the trailors and so does lair, wat if killzone looks better than the trailor?!

Halo 3 is by no means a "graphical stunner".  The graphics of HL2 on my high-end PC are better, and that game was released 3 years ago.

Sorry, a bit off topic, but I was genuinely confused when I read that line.
