Some of the highlights Kertz posted include:
Yes, there will be spotting.Further details about Battlefield 3 have also been revealed by retailers now offering the game for pre-order. Most notably, Gamestop states that urban combat will be a big part of the game:
Dolphin Diving is out. Period.
Vehicle/Infantry balance is a focus for me, it will be awesome this time.
No plans for ziplines or grapple hooks no.
Yes, prone is on all platforms.
BF3 will be deeper than BF2. That said we've paid a lot of attention to keeping depth while pacing the learning curve.
BF3 is the sequel to BF2. It's not BC3.
Friendly Fire will be an option, yes.
No comment on commander.
Yes, there is bullet drop. Doesn't work the same as BC2 though, it's a much deeper system.
No, no tracer darts. That's a bit too BC and not enough BF.
No, I won't confirm any vehicles from the teaser.
One of the cities is Tehran... Yes, yes there will be sand.
"Take the fight to iconic and unexpected places in the USA, Middle East, and Europe including claustrophobic streets, metropolitan downtowns, and open, vehicle-friendly landscapes as you fight your way through the war of tomorrow."
