Is a Pretzel Pizza in the Works for Pizza Hut?

Pizza Hut recently filed as trademarks a series of names that hints at future pizzas from the chain, or perhaps a new line of pizzas to come. The names aren't a lot to go by, but they do take a bit more artistic license than usual.

One in particular, the "Pretzel Piggy," suggests that a pretzel crust, similar to the one currently being offered at Little Caesars, might be in the offing (I'm going to hope they don't go with cheese sauce instead of tomato).

Here's the full list of the names they filed as trademarks:

- Old Fashioned Meatbrawl
- Garden Party
- Cock-A-Doodle Bacon
- Giddy-Up BBQ Chicken
- Pretzel Piggy
- Cherry Pepper Bombshell
- 7-Alarm Fire
- Hot and Twisted (maybe a spicy pretzel crust pizza?)

Update 10/28/14 - Here's a screenshot of what appears to be a pretzel crust pizza from the Pizza Hut website before it was pulled:

There's also a pizza on the left that looks like a thin crust with jalapenos, chicken, and what I'm guessing is a spicy sauce (maybe the currently trendy Sriracha?).
