Hmmm, we're really going to have to watch the expo, though I kinda doubt they'd want to put a coaster there with it being so close to the road, and so near Echo Hollow where it would disrupt things.
There have been various rumors sprouting up recently about them re-doing the Landing, but I haven't heard one I like yet. That area really needs to keep its quaint, center-city feel - any sort of new ride would really start making the entire park feel more like a big amusement park than an actual city.
We've talked about this before, but back in 2005 they nearly put the Grand Expo there, and I think it was Mary Herschend who stopped them. Let's hope they keep to their senses.
