As usual, I'm ambivalent about the news.
On the one hand, some of the new stuff sounds very cool. I adore Buzz Lightyear's Astro Blasters, so the upcoming Toy Story Mania sounds neat (I'm a sucker, apparently, for interactive rides...not a surprise, really, given how much I loved Horizons). Patrick, being the Disney history buff that he is, will love the interactive Walt Disney Story.
But on the other hand, I kinda like DCA as it is today. It's lower-key than Disneyland, but I like that. I like feeling like I can meander through the park and take my time. I don't feel pressured that if I don't zoom through all the attractions that I'll miss something.
So, we'll see.
Of course, if they can make it look as awesome as DisneySea, all will be forgiven.
