I am going to speak up for Jrb1979, I don't know how more people aren't disappointed. That was a terrible day and it left unused spaces with no future plans. If the annoucement didn't come today, it speaks to nothing occurring for a long time.
I do get the excitement for HEA, and I am excited for it too! I WANT to see in on a future trip to WDW! However to me, WDW could only expect they were going to get a firework show post your 50th anniversary. It was going to be either HEA, a brand new one or another one coming back. So it wasn't a question of "if", just what was it going to look like.
For me, today isn't just about filling out the details on the obvious things that would/should happen, it's about a little new magic.
