They haven't even finished putting the track together, so I'll withhold judgement on the amount of theming until opening day.
Honestly though, even if it is just the station that is highly themed, I'd take that. I really wanted some tunnels or buildings to fly though, but I'll take what I can get. Wildfire comes off just fine, and I consider that coaster highly themed. We'll see what happens with that launch building though. That could turn into something big.
We can be certain that this coaster has a detailed story of it's own - probably even a theme song like the last several coaster/big ride additions. They haven't slowed down on theming yet. Fireman's Landing still looks great even if some of us don't like the prevalence of rides up front. Lightning Rod's station is supposed to be pretty good as well.
