I'm told that Alton Towers has officially removed the VR system from their Galactica coaster for the 2019 season. The excuse is that it was being removed to improve guests requests and satisfaction ratings, but I'm also not surprised either, because the same style system was also removed from Kraken at SeaWorld Orlando a little over a year after it was first installed for similar reasons.
For the time being Galactica, formerly known as Air, will keep the Galactica name and themeing for the season, though what happens beyond 2019 is anyone's guess right now.
Alton Towers has also confirmed that their new on-site horror attraction, “The Alton Towers Dungeon” will open on March 23, 2019. There will be an additional charge to experience this attraction.
