Universal on Ollivander's Shop
From the press release, we're given an idea of what we'll find at the upcoming Harry Potter World:
"With the assistance of a live actor, along with amazing special effects, guests of Ollivanders will get to experience the same type of magical moment Harry had in “Harry Potter and the Sorcerer’s Stone” when a wand ”chooses them.”
"When guests visit Ollivanders, they will instantly feel like they’re in the shop from the films. It’s an intimate, single-windowed building, with the same signs, colors and other details read about in the books and seen in the films,” said Alan Gilmore, art director of the Harry Potter films and The Wizarding World of Harry Potter. “But more importantly, visitors to Ollivanders will experience for themselves the magical moment that forever changed Harry’s life.”

In addition to the magic featured in Ollivanders, guests will experience many other magical happenings at The Wizarding World of Harry Potter, including a Howler featured in the Owl Post shop front window whose ranting can be heard by guests as they pass by; The Monster Book of Monsters in Dervish and Banges that will snarl and growl at anyone who tries to get too close, and the Hog’s Head which can be seen puffing his jowls at visitors who visit the Hogshead pub.
