If you pre-order ME3 you get N7 armor and a gun. You can pre-order the From Ashes dlc its an extra $10 and it comes with a code on the receipt. But, no it doesn't come with a pre-order.
man, I want to play Journey so badly. I'm a PC player, and don't own a PS3 though :( I just hope the soundtrack will be released soon. What I've heard of the soundtrack is on the level of awesomeness as Jeremy Soule.
