I have not been overly excited about this by itself. I grew up with Mickey hugging and using gestures etc., not carrying on a conversation with me.
When I look at the big picture, I see where this is going and how immense the level of magic will be on the most personal of levels. This has me optimistic about the future of in park interaction, and all of the many different directions this can go and all of the doors this is going to open. The only issue I see is the ammount of infastructure that needs to be in place to execute these goals properly. Without a nearly flawless execution, all of the R&D will go to waste and all the millions of possibilites that could come out of this and the RFID tech will go right out the window. Im very excited to see how this will tie into existing tech / attractions as well as come together with new tech (RFID) to create a cohesive magical experience that is so unique even the avid and frequent WDW guests will have a whole new experience. And not just in M&Gs but all throughout the parks. Just think of the possibilites!
