We still have more questions than answers about the Wizarding World of Harry Potter more than a year after plans were announced for a West Coast version of the themed land at Universal Studios Hollywood.

With much of the what, where and when of the Wizarding World project still a mystery, let's start with what we do know before working our way to what we still don’t know.

Where will the new land be located?

After months of rumors, Universal announced on Wednesday that the 40-year-old Gibson Amphitheatre located on the theme park grounds will be torn down to make way for the Wizarding World attraction.

The adjacent Adventures of Curious George water play area will also be removed, suggesting a possible main entrance to Wizarding World.

The new themed land will be squeezed between the studio backlot tram station, the WaterWorld stunt show and the Shrek 4-D movie theater — all of which will not be affected by the expansion.

When will construction start?

Universal announced this week that construction would begin in "late summer." Gibson Amphitheatre officials said the 6,000-seat concert venue would stage shows through September.

How much will it cost?

The overall project, which will include facility and infrastructure upgrades at the adjacent television and movie studio, has been pegged at $500 million.

The original Wizarding World, which opened in 2010 at Universal Studios Florida, reportedly cost $265 million. Presumably there will be fewer start-up costs this time around.

How big will the new land be?

Universal officials have said that the California Wizarding World will be similar to the Florida version.

But the 6-acre Hollywood site will be about half the size of the 13-acre Orlando location. But two-thirds of that land in Florida is dedicated to the Dragon Challenge dueling coaster (which most likely won't be replicated in California).

What attractions will be added?

The Harry Potter themed land in Florida includes three attractions: the Harry Potter and the Forbidden Journey motion-based simulator ride and a pair of re-themed coasters, the dueling twin-track Dragon Challenge and the family-friendly Flight of the Hippogriff.

Universal officials have said that the California themed land would include a clone of the Forbidden Journey ride inside a replica of Hogwarts castle. What remains unclear is whether Hollywood will get a Hogsmeade village complete with a Honeydukes candy store, Ollivander's wand shop, Zonko's joke shop and a Three Broomsticks restaurant.

When will Wizarding World open?

The "when" of Wizarding World still remains a closely guarded secret.
