LittleBigPlanet Vita could release on September 21, according to an updated release schedule published by GAME.

VideoGamer spotted the date on the retailer's website earlier today alongside revised release dates for PS3 kart racer LittleBigPlanet Karting, PlayStation All-Stars Battle Royale and Uncharted 3: Drake's Deception Game of the Year Edition.

According to the website, PlayStation All-Stars Battle Royale will follow two weeks after LBP Vita, hitting both PlayStation 3 and PlayStation Vita on October 5.

LittleBigPlanet Karting will allegedly follow a month later on November 9.

Uncharted 3's Game of the Year Edition, meanwhile, will ship on September 21, the website says.

Retailer release dates, of course, should generally to be taken with a pinch of salt. However, GAME's decision to revise release dates for a variety of first-party Sony titles could suggest that the retailer knows something the rest of us don't...

Sony declined to comment when contacted by VideoGamer.
