Heard the promo for the Dick Clark program yesterday and it is the 40th such event. That will tie in with WDW 40th anniversary. It seems they didn't do much for the 40th back in October so maybe this will be a new promotion to celebrate the 4oth ...
They never intended to make a big deal out of MK's 40th.
They have already had a national "100 Years of Magic" promotion and a
"50 Years of Magic" promotion.
Subsequently hauling out a "40 Years of Magic" promotion would be a bit anticlimactic, as well as unexplainably silly.
What's more, 40 years in business is not at the same level of "milestone" hierarchy as 50 years or 100 years.
Half-century and century marks are automatically more dramatic.
What's more, MK's 40th (and MK not being the "first" theme park) is not related to DLR, and this promotion is to include both parks.
All that said, I have no idea of what the announcement will actually be.
(I know it will relate to "time" in some primary way, of course... CLOCKS being the "teaser.")
But, I, like some others here have opined, anticipate that "big announcement" will be a far less "important" or "exciting" situation than many have been led to expect.
In that vein, do expect nearly everyone on the DISboards to be disappointed in its lack of substance.
