I don't know how new these are but they showed up in our company cafeteria a couple days ago... and I like them a lot.
Even though they are called "buffalo wing", they are essentially a cayenne pepper & vinegar sauce flavor on their pretzel bits, and are vegetarian. The ingredients list isn't too scary either.
They do have a lot of fat, though. I've been a fan of the honey mustard 'n onion flavor for some time.
I thought I read that originally the 'pretzel bits' line came from "what to do with broken pretzels that we can't put in a bag of pretzels" and that they're now popular enough that they have to specially manufacture enough 'bits' to meet demand. But I don't have a source for this rumor/fact.
