One issue I keep thinking is that they are pushing Frozen in a lot of small ways, no large scale plans have been announced. Ya, you could count the Maelstrom overlay as a big ticket item, but even that is just an overlay and who knows how good it will be done (if it even does go through). My point is that perhaps they are in such a mad rush to get Frozen in the parks that maybe they will over saturate it before they can give it a proper presence on a large scale such as a big new E ticket and by then people will just be sick of it or they will have too many Frozen attractions and the vanity will wear off.
I think its great that they are acting quickly and not just sitting on a hot IP, but are they approaching this with a long term plan or just scrambling to make something happen in the wake of Potter being a huge hit and are now desperate to stay in the headlines? My fear is that they are doing many small things as a hedge against loosing the excitement over Frozen and with this they will diminish the value of what would otherwise be a big announcement if they decide to actually build an E ticket attraction for it . Yes, they could do a million small things now and then build a new attraction for it years from now and people will still flock to it, but Im thinking in terms of strategy, not just flooding the parks with Frozen NOW and then make an announcement a year later about something major. It may come off as if they are desperately clinging to Frozen to solve all their attraction capacity issues. If they announce SW Land it will even out nicely, but we have no clue what the time frame is for that.
As I said, these are just thoughts, I could be waaaay off. Im actually proud of Disney for being pro-active with this, I just dont want them to to get too ahead of themselves and miss a larger opportunity to steal some thunder from Uni. And ya, I know they dont NEED to steal any thunder and the parks will be just fine regardless of what Uni does but I LOVE WDW and want to see them get back to firing on all cylinders and staying so far ahead of the curve that nobody can even see them or where they are going next.
