You completely missed the point about Next Gen being far more than just an upgrade and web/smart phone enablement of Fastpass. Full details of the project haven't been made known to anybody publicly. But, from what has been leaked, they include other things like queueless waiting lines and interactive queues, guest management and crowd control. I know they have filed at least a couple of patents for some of the ideas, one includes an upgrade to busses on demand to do guest on-off counting and then more accurate forecasting for park closing and how many busses will be needed. This might also integrate with some of the RFID technologies rumoured as well. The point is, the rumored billion plus dollars is for R&D of a lot of different ideas and technologies aimed at improving the overall guest experience.
