On its Facebook page, the company posted a picture of a taco, as well as packaging for Doritos Cool Ranch.  They followed up on their Twitter page by saying "Anything could happen in #2013."

Taco Bell had already announced that it will be adding at least 2 new menu items this year.   And why not?   The Doritos Locos Taco that they introduced in 2012 is the company's best-selling new product ever, with over 250 million sold so far.
