I'd much rather judge by the actual content than just the name. If this new development is an improvement over what has come before it, I probably wouldn't care if they were still calling it Hyperion Wharf or even just "hey look over here we have Disney stuff."
While the Downtown Disney name is going to hold nostalgic value for some that grew up with it (just like Disney Village will for others) I think the area saw such a decline while under that banner I'd rather see a new name used to help separate it from the whole debacle as much as possible.
I'm struck by just how closely Disney's downtown district is following the same trajectory as many other cities' downtowns - early popularity led to growth and expansion, but as the crowds began to wane the entire area began to fall apart. Now we're at the beginning of the massive gentrification phase designed to revitalize the area and bring people back to downtown.
And I really hope it the project is successful. I want to like going there far more than I actually do, and since Pleasure Island disappeared it is nothing more than a place to get souvenirs without having to brave the theme parks.
