Video game delays are nothing new, but 2012 has certainly seen its share of disappointing setbacks. From title launches, to DLCs and full console releases, gamers shouldn't hold their expectation too high for some of these release dates. Enthusiasts have gotten a preview of what's to come with conferences such as E3 2012, the EA Summer Showcase, and Gamescom 2012, which kicks off tomorrow. But for some launches, the work that goes into crafting the final product may take developers and publishers longer than they projected.

Which of these delays bothers you the most? Check out our list of seven setbacks that have been announced for 2012.

1. Wii U Release In Europe. Sources connected to the matter exclusively told CVG that manufacturing problems may keep Nintendo from finishing the Wii U on time for its November 2012 release date. The launch is likely to be pushed back to December across Europe, and the main issue involves manufacturing the console's GamePad controller. The source also added that Nintendo is actively working to release the Wii U before Thanksgiving in the United States, but Nintendo has declined to comment.

2. "BioShock Infinite." Fans have gotten a peak at some of the characters they will be facing in the third chapter of "BioShock," such as the Motorized Patriot and the Boys of Silence. A release date of Oct. 16, 2012, was originally set, but it was reported in May that the game wouldn't be launched until February 2013. "BioShock Infinite is a very big game, and we're doing things that no one else has done with a first-person shooter," creator Ken Levine said in a statement.

3. "Skyrim" DLC "Dawnguard" For PS3. It may not be the biggest video game release of 2012, but it is incredibly frustrating to fans of the "Elder Scrolls" franchise. The "Dawnguard" DLC, which follows a character throughout their quest to either play as a vampire hunter or one of the blood-sucking creatures themselves, was released on June 26 for Xbox 360 owners. Now, more than a month later, the DLC has been launched for PC players, but no release date has been announced for PlayStation 3 gamers. "We are not satisfied yet with Dawnguard's performance on the PS3," read a recent post on Bethesda's official blog in early August.

4. "South Park: The Stick Of Truth." The new video game to come from Trey Parker and Matt Stone's hilariously offensive cartoon looks like it will be just as funny as the acclaimed series. The pair showcased a demo at E3 2012, but fans will have to wait until March 2013 to hear more about this.

5. "PlayStation All-Stars Battle Royale." The PlayStation-branded fighting game, which will feature some of Sony's most recognizable characters, has been pushed back to Nov. 20. The game, which is similar to Nintendo's "Super Smash Bros.," has been pushed back according to the official PlayStation Blog. "Our goal is to deliver a fun, well-balanced and compelling gameplay experience that pays homage to all of these incredible characters," SuperBot President Chan Park wrote in a statement. "We also know our fans have high expectations for this title, and to that end, we have decided to move the release date to November 20 for North America (including Canada) and Latin America territories." This is a little more than a month past its original Oct. 23 launch date.

6. "Tomb Raider." The reboot of the classic 1996 PlayStation adventure game, will be delayed until the first quarter of 2013. Crystal Dynamics, the developer, said that they want to "put finishing touches into the game." The forthcoming "Tomb Raider" release will feature a younger, inexperienced Lara Croft, who gets separated from the rest of her crew after being caught in a storm. Croft becomes separated in Japan, and will now be released months later than its original holiday 2012 launch window.

7. "Aliens: Colonial Marines." This shooter was announced in February 2008, and in September 2011 publisher Sega confirmed that it was still in the works. Now the previous fall 2012 release date has been pushed back to February 2013. The Gearbox shooter is one of the titles that will be available with Nintendo's Wii U post-launch, and is sure to incorporate the console's GamePad controller.
