I'm sorry, did I miss something? Did the game come out already? Seems to me the game would need to be released first, and I could have my dates all mixed up but I thought the game was coming out tomorrow. But I could be wrong.
Also - and this is simple curiosity on my part - have there been any developers who talk about DLC before a game actually launches, or even within, say, seven days of launch? Just curious.
Well there's the http://www.kotaku.com.au/2012/10/assassins-creed-iii-season-pass-adds-alternate-history-campaign/ for Assassin's Creed 3, and when they showed Splinter Cell: Blacklist at E3 2012, http://gameshotpedia.com/e3-2012-dlc-filter-blacklist-splinter-cell-in-an-image/, before a release date had even been announced for the game. Also there's numerous games that sell season passes for future DLC at, or even before, release.
