I snuck a look inside one of the boxes at work today and it turns out that the new "Doritos Burn" flavour is indeed a hot chilli flavour. This in addition to their existing 'hot mexican salsa' flavour. (then on the way home I saw that Woolies already has them out on shelves, and on special - just that flavour)

It's definitely a hot flavour, but builds up after a few chips. It doesn't just hit you with a burning sensation from the first bite. It could be hotter, but I don't think they would sell to the masses if it was.

And there is a cross promotion with another brand of theirs - Pepsi. On the back of the pack it says to 'light your fire with doritos burn' and 'cool the burn with Pepsi Max Ceasefire Lime', with a pic of the new lime flavoured Pepsi Max bottle. (a soft drink flavour that hasn't arrived at our warehouse yet, nor was it at woolies)
