We've gotten word that two new "NextGen" initiatives are being undertaken by Walt Disney World at Disney's Hollywood Studios. NextGen is the colloquial term for the anticipated (but not officially confirmed) next generation guest experience in Walt Disney World.
First is for the Rock 'n' Roller Coaster, which will receive "NGE Queue Modifications". The Tower of Terror and Star Tours have already or are in progress of receiveing similar upgrades. The timeline for this addition states work will begin today, April 16 and continue through May 11, 2012. Guests are unlikely to notice anything.
In addition, there are plans for "Parkwide WIFI for NGE". We assume this means that internet connectivity will be added throughout Disney's Hollywood Studios to support these NextGen updates. Work for this will progress through June 15, 2012.
