Disney has just announced MagicBand+, a new wearable wristband that will unlock new interactive experiences that react in real-time in the parks by lighting up, vibrating, and more. Here is Disney's official list of some of the interactive moments guests can experience with MagicBand+:

• Play like a bounty hunter in a galaxy far, far away and find virtual bounties throughout Black Spire Outpost in Star Wars: Galaxy’s Edge at Disney’s Hollywood Studios. 
• Interact with the “Disney Fab 50 Character Collection,” the golden sculptures spread throughout the Walt Disney World theme parks.
• Experience nighttime spectaculars in a new way as you see your band light up and complement the magic in the skies, including the new “Harmonious” at EPCOT and “Disney Enchantment” at Magic Kingdom Park.

Interestingly MagicBand+ will retain popular features from the original MagicBand wristbands as well, with guests still able to use it for hotel room entry, theme park admission, dining reservation check-in, and PhotoPass links. 

MagicBand+ wristbands will be available for purchase beginning next year, including a discounted, pre-arrival price for Disney Resort hotel guests as well as new and renewing Walt Disney World Annual Passholders. No specific price points have been shared just yet. Disney has also confirmed that regular MagicBands will continue to be available next year as well.
