i'm quite liking the 3 bonus maps (pre-order maps) i've got from the game-market place, i don't think the multiplayer (player vs player) DLC that will be released isn't in my intrest..... with that being said; i am looking forward if the "Rumored" Unreleased Mercenaries maps will be released via DLC in the future. as for the title update coming in mid-December, i wouldn't call it a "DLC" more so, of being just a mere title update.
i figure if the "Rumored" Mercenaries maps will be released, i am looking at a late January or mid-Feburary release..... as for the Rail-Yard map, i thought that the enemies were of the Infectees, instead of the J'avos, since the level it self is from Leon's campain, but hey. i'm some-what content about it being the J'avos instead of the Infectees.
