It's been said before by EA that if someone's going to "kill" the Call of Duty franchise, it's not going to be by copying, but by making a better shooter and that point's been reinforced yet again, this time by Battlefield 3 game designer Alan Kertz.
As reported by VG247, Kertz said that "you don't kill CoD by trying to be CoD. You kill CoD by making a better shooter."
In addition, Kertz also noted a couple of details on Battlefield 3 during a Twitter Q&A session with the fans, including:
The ability to prone.
Destruction, vehicles and visual quality is of important to DICE.
BF3 is using an upgraded FOV system from Medal of Honor and Bad Company 2.
There is a limited edition for console versions.
Tehran is confirmed as one of the locales.
Unlikely for there to be a server browser on console version, so no 64 player matches there.
Expect an proper announcement and reveal around GDC. DICE released the Battlefield 3 teaser trailer a couple of days ago, be sure to check it out.
