Talking "Meet and Greet" Characters

Disney has introduced some talking "Meet and Greet" characters.  These are just tests but we imagine we will see many more of these in the future.  Check out Mickey Mouse below.

They have been doing some form of talking characters for a while now, but not with main Disney characters.  Check out "Push" who we have seen a few times at the park.

Or course, "Turtle Talk with Crush" is a great success and uses the same technology.

What do you think?  Has Disney gone overboard or would this have been part of Walt Disney's dream?
