I like that they've already narrowed it down to four options, on top of the fact they're hinting that the associations with the current name reside in the mud. Here are the four choices:
Parkside • Riverfront District • Park District • The Banks
My selection: It was a good idea to leave the current name in there, because along with being the current crowd favorite, it also saves on rebranding everything. Parkside and Park District sound too Buckhead-ish to me, and honestly, any neighborhood with the word "park" in it should reside near one of the city's storied parks (i.e. Eden). Our city's park system has a rich history, and the most notable ones lie inland - I just can't make the connection with riverfront. Thus, I picked Riverfront District. It's not flashy, and doesn't have that staccato ring to it like The Banks, but it does remind me of the Riverfront Stadium glory days, while being helpfully obvious to out-of-towners, newbloods, and the like. I do like the The Banks, and honestly, I wouldn't mind if they kept it, but a new name with the new steel going in makes a lot of sense.
The current results of the poll are here.
• NOTE: I'm not digging Sawyer Point or Friendship Park by any means, nor the planned Riverfront Park, because I think they're all great & necessary additions to downtown, but they didn't build the city's rich heritage, they've only followed in their footsteps. Personally, I've supported and followed almost all of the city parks, and encourage their continual beautification and growth, but as far as the renaming of the new district on the river is concerned, I associate "banks" and "riverfront" with it much more than "park".

• Update (3/6/9): A funny writeup over at The Banks Blog on rejected name suggestions, and many other discussions on this topic floating around, like at Quim's and Pepper's blog.
