I don't think it's really intended to be ground breaking.
This is more Disney's way of saying, "look, we still have water parks, come visit" before VB opens.
Eh, not really. March 12 is when the park reopens from refurb and people have always suspected it to open then.
From the look at recent aerials (some with running water), it's pretty much read to go. Just some more landscaping needed before opening.
