https://twitter.com/#!/masseffect/statuses/169555470636417024 NA/CAN only More info go to EA's twiiter - https://twitter.com/#!/origin_EA/ Expires 5th March and pre-order ME3 for any platform (PC/XB360/PS3), you will receive a bonus digital copy of BF3.
Just to add to the post as further confirmation. I talked to a EA representative earlier and they confirmed that you can purchase any copy of ME3 for any console and still get the digital version of BF3 free. They will send you a code when ME3 releases that would probably be redeemable through Origin. Wanted to get that out there, because I was being hesitant for that reason too. Great deal
