It's been a while since my hard decision to buy either Battlefield 3 or Saints Row: The Third. 
 
 I was going to pre-order Battlefield 3 because of it's Back to Karkand expansion pack. Karkand was my favorite map on Battlefield 2, but now Karkand is on Battlefield 3!? Now who knows what destruction can go on with that new Frostbite Engine (Especially those destruction physics)! 
 
BUT NOW, Saints Row: The Third now has a pre-order bonus, which is a costume and a few other wacky stuff. This pack is called Professor Genki's Hyper Ordinary Pre-order Pack.

Battlefield's pre-order bonus is still better though
 
One thing to tell you though, I'd give my money to Battlefield 3 if I had a PS3.
