So apparently Dice and EA have released a series of "shortcut bundles". They're basically "pay to unlock" bundles for each class, ground vehicles, and air vehicles, or you can buy the "Ultimate Bundle" and get it all at once.
Now, I sort of have mixed feelings on this. I know a lot of people don't get to play the game too much and those people might like to try some of the other weapons that are hard to unlock. I myself thought about getting the air bundle just because I can't even get off the ground without getting shot down because all the other pilots have so much better gear than me.
However, these bundles aren't cheap, with the Ultimate Bundle being $40. That's 2/3 the price of BF3 ITSELF. Also, it, in my opinion, kind of ruins a lot of the replayability if there's nothing left to unlock in the game.
