All in all, it is pretty underwhelming - it is basically what we knew from D23 Expo last year with the addition of a few new re-theming of attractions in Paris. No third park announcement for Tokyo or details on the Avengers land in DCA or anything like that. Guess we'll need to wait until next year in Anaheim!
