What Disney says and what they mean or what their real reasoning is can be two entirely different things. Saying they want to lock in their guests experiences 60 days prior and keep them on property sounds like a reasonable gimmick, but who knows if that is their actual reason. I've heard a lot of people deciding to leave mid day and do other things at other places...ergo defeating the FP+ purpose, wouldn't you say? I don't know. I think their real purpose is more data collection/tracking. The MBs are little data tracking devices. This is what our guests did during the first half of 2014, here's what they spent, where they went, yadda yadda. That makes more sense to me and a 900M dollars to accomplish that, facilitate park entry, shopping, etc., is a drop in the hat for them. Come on...you didn't REALLY think they'd tell you exactly what they are doing and why? Paper FP's were going to be on their way out in some manner. They had them for a while, tweaked them, and now they are moving on to a more 'trackable' method of operations. FWIW.
