Disclaimer - while this has been confirmed by several sources from inside TDA, it's no where near official!
I have it on good authority that a new fireworks show will debut in April, and the current plans are to retire "Remember, Dreams Come True" this November. Four sources, all from Disney, have confirmed this, but I am not sure if i trust two of them.
The point of this post is, make sure to see it now if you haven't yet, becuase it sounds as if it will be going away.
Rumor has it the new show will be shorter, new sound track, less pyro launch sites. Also hearing that Believe in Holday Magic will be touched up and will utilize some of the same pyro launch sites used in "Remember" used.
I'll let you know if i hear more. Hasta folks!
