When Resident Evil: Operation Raccoon City did not appear at the Tokyo Games Show, some press started to question whether the game would be out by the projected Winter 2011 release window.
Kotaku contacted Capcom and asked if the game was still on target for the Winter, and they responded that Operation: Raccoon City was "definitely locked in for winter."
Keep in mind, "Winter" rims from December to March, so it's entirely possible for the game to make a "Winter 2011" release, but be released on March 2012.
