As much as I know that Disneyland isn't implementing Duffy at his full potential, I'm already in love with him, so much that I asked my aunt to bring me back a Duffy from Walt Disney World for Christmas - even though we're going to Disneyland in a couple months. Maybe it's because I know how special he is at Tokyo.
DuffyDaisuki, I still need to read over your longest post, but I read through the one above that. You said "Obviously, this only works if, as Malin suggests, WDC actually has people in planning and promotion who are doing more than their jobs - who actually believe in "birthing" a character." I agree. But it doesn't seem like the executives know what they're doing with the bear. The only one who truly seemed to love Duffy was Danielle DuBois, Disneyland Ambassador, which you'll notice if you watch his welcoming ceremony from DCA: YouTube - Duffy Makes His Debut at the Disney California Adventure
It's unfortunate that she doesn't have more power to do something with Duffy. She even took the time to mention Tokyo, his popularity, and his back story. I truly hope that Disney gets it into gear and is able to make Duffy a part of the parks just as he is in Tokyo.
