I'm always thrilled to see new theme park plans. Watching these projects develop (and hopefully actually be built) is incredibly interesting.
That said, I can't help but worry about the location. If they're looking to be a stop-off point for Disney and Florida-bound tourists, they're 4+ hours off the normal North East's/Mid-Atlantic's Home -> Orlando route. If they're looking for regional pull (Nashville, Knoxville, Charlotte, Birmingham, Montgomery) a fair number of those markets already have big competitors (Dollywood for Nashville and Knoxville plus Carowinds for Charlotte). As icing on the cake, Atlanta's local population base already has Six Flags over Georgia- one of the most charming Six Flags properties out there.
I can see a new theme park in Atlanta siphoning off some of the deep south's previously Universal-bound tourists (from Arkansas, Louisiana, Mississippi, and Alabama) as they really don't have much alternative right now, but is that enough to sustain brand new theme park construction? If it is, why not build somewhere between Texas, Missouri, and Georgia? Jackson, Mississippi? Memphis, Tennessee? These are big, completely uncontested markets. If seems like if they wanted to bandwagon on existing amusement park tourism markets, they should be going to Florida or California and if they wanted to carve out their own footing, they should be looking at a nice large, uncontested market area. Atlanta seems like the worst of both worlds...
I hope this moves forward and is ultimately built because if it is, I'll be there in a heartbeat. That said, the speed at which I'd visit wouldn't be solely out of enthusiasm for the park, but more out of worry that we could be looking at Hard Rock Park v2. :-/
