Taco Bell will announce today that it's launching its next Doritos Locos Taco on Aug. 22 -- but it's holding back on what exactly that flavor will be.
A spokeswoman for the chain said that it can't release further information, and that the Twitter and Vine announcements are meant to fuel speculation and excitement among fans.
Here's the planned tweet: "@Tacobell: Nacho Cheese. Cool Ranch. What's next? It's coming 8.22.13. #_DLT"
The chain said that it will be bringing "mas heat" this summer with the arrival of the latest Dorito Locos Taco. Based on that phrase, our best guess is that it will be the Flamas taco, a spicy red taco shell with a hint of lime flavor based off of a Doritos chip of the same name, which Taco Bell tested last year. It may end up having a different name for all we know, but CEO Greg Creed has mentioned in various articles this year that the spicy chili-lime taco was his favorite.
Less likely is the Fiery Chicken Cool Ranch Doritos Locos Tacos, which the chain is said to be currently testing.
Taco Bell in June did a social-media tease of the newest taco. At the time, it made no mention of when it would be available or what it would be, but Instagram and Vine videos showed "New DLT" spelled out in flames -- another indication of the spicy flavor.
The Doritos Locos Taco, first introduced in March 2012, was the biggest and most successful product launch in Taco Bell's history. A year later, it unveiled its Cool Ranch Doritos Locos Taco, and by May, the chain said it has sold more than 500 million of the tacos total.
