On Origin, pre-order ME3 (doesn't matter what system, apparently) and you will receive a free digital copy of Battlefield 3 for PC.

Deal ends 5 March 2012. It's two amazing games for thirty dollars each, essentially. Great deal considering BF3 is five months old and fucking awesome.
EDIT: Pre-order it myself. Origin will give you a code for BF3 once ME3 comes out.
EDIT 2: EA's being a dick... no more free BF 3...
