Rumor has it that market research company Greenfield Online is preparing a plan for Burger King to sell promotional Xbox 360 games in their stores. The games would apparently riff off "the most popular game types," adding the super-creepy Burger King character to an action, fighting, and racing game; customers would have the option of purchasing one for $4 with any Value Meal.

No telling if there is any validity to the rumor, but Burger King has already ventured into in-game placement, most notably in the EA Sports title Fight Night Round 3 (click the banner on the bottom left of the BK homepage). The concept art attributed to the Greenfield leak is pretty questionable, but it's just that, concept art. More than likely this is an idea under consideration, but not necessarily execution. I may take issue with the idea of slapping BK into existing game genres, but retail distribution of unusual titles has promise.

Update: Kotaku has confirmed that Greenfield Online is in fact doing this promotion. In fact, the group has threatened to sue Kotaku, claiming they are violating their intellectual property rights. Read the letter from the lawyer here.
