There are tons of simple designs that looked cool. Great even. The WWF title from the 80's was fantastic, as was the Eagle belt of the 90's.. not to mention the countless titles produced by Pacific Northwest Wrestling, AWA, and the IWGP back in the day, and even nowadays with the ROH World Title, the PWG World Title, and countless others. I like basic designs that ooze prestige. All they really need is a big slab of gold with some flags, a globe, an eagle, and maybe some silhouettes of wrestlers on it to make it a good belt, but I imagine they're going to go a bit over the top.
Who knows.. we'll see when it debuts I imagine.
