I imagine they'll have a better idea of what combinations of products and displays sell better. I'm thinking along the lines of: "1000 people walked past display stand A and 100 bought the product. 2000 people walked past display stand B yet only 50 bought the same product." Use this kind of information to correlate what works best where. Up till now, everything is collected by hand; someone standing with a counter, pressing a button, a labor intensive way to collect data. More detailed information should help them maximize POP sales.
However, I can't imagine this generating more than a few million in additional sales. The big money must be elsewhere.
Here's a couple links I posted in another thread (
Numbers, Cars and Quality ...) about how Target uses this same capability to drive advertising, plan store layout, etc.

In a lot of your posts, you're too focused on direct monetization. There's certainly going to be some revenue tied directly to this system, but there's no way that they can make back that investment through direct means alone.
The basic idea is that increased sales are great, but just as important is that better targeting leads to better brand identification. If you get advertising that's tailored directly to your interests, you get a better impression of the store that goes beyond the first order sales and leads to much higher sales over time. How much more fun is a catalog where there's something cool on every page than the old Sears catalog with a few sections directed at you and several sections that you'd flip through quickly because they were aimed at different demographics. If they can arrange to give you more messages aimed at your specific interests, it increases the chances that you have a positive impression regardless of the overall quality of the offering.
That's the theory, anyway. I don't believe that it necessarily makes sense to run theme parks that way, but that's what their thinking is. For every Target that gets it right, there are dozens of Kmarts/Sears, Circuit Citys, and Borders that flame out spectacularly.
In some ways, this is the ultimate Presslerization of the parks.

I'm also fairly certain that quite a lot of the budget is tied up in infrastructure that IT needs and has probably needed for many years, but never got because they couldn't make a convincing enough case for (happens to IT groups everywhere). Eddie Sotto had an example where they need to do some refurbs on an attraction but could never get the funds, so they had to spin it into a reimagineering project tied to some new characters that could be marketed to bring in new visitors.
