It looks pretty nice. However I wouldn't upgrade my acct just to fly in one of those. That's paying real $25~$50 to fly a fake hot-air balloon around. =P It's still a nice update but I think the main focus should be on working out the already existant problems of the servers rather than build new technology that only a select few will be able to use.
In the meantime, a new planet in Zone should be created so it could be tested further, as well as GK. (If BM (G2K1) was still around I'd suggest that instead but that server doesn't seem it will be up any time soon.) Test out how Dropships could act and maybe make some types of elevators in the bases? Some jetpacks that actually jet?? I think that would be cool.

That mech world idea someone meantioned earlier sounds like a good idea!
It has a lot of potential. After it's released more info should be shared about it, such as how other players can see it, if there is an ammo count, if someone can steal it etc etc.
