Well lets see...

1. BF3 is bringing a more cinematic experience through knife kills (a la Halo Reach-like assassinations) and much better character animation, as well as building even more on Destruction and fine-tuning it.

2. Supports hold the line by laying down suppressive fire, and give out ammo. Assaults attack objectives and heal/revive people. Engineers blow shit up, blind people in CQB, and fix vehicles. And Recons hit people from far away, throw motion sensors to find the enemy for allies or themselves to clear, and lay traps with C4.

3. B2K will be updating Gulf of Oman, Strike at Karkand, Sharqi Peninsula, and Wake Island by bringing them from the BF2 Refractor engine into BF3 with the Frostbite 2 engine. They will be completely reworked for destruction, allowing buildings to be toppled rather than block one's path, as well as receiving a graphics overhaul with the new engine.

4. You should play BF2 for the maps, 2142 for the classes, and BC2 for the destruction. Quite a list, I know, as they all have an element being implemented, but they will teach you to become prepared for BF3. If you can't get BF2 though, Battlefield Play4Free is another option, but Wake Island isn't in it (yet). It also is styled after BC2's classes and has role playing game-like leveling.
