ABBA will release their first new song in 39 years and embark on a hologram tour as their younger selves - but that's not all.
Agnetha Faltskog, Anna-Frid Lyngstad, Bjorn Ulvaeus, and Benny Andersson, the renowned Swedish band, are foreshadowing a major announcement next week with the introduction of a new website.
This morning, the ABBA Voyage Twitter account sent out a message with a link and an invitation.
Along with the date "02.09.21", there was also a picture of four gold circles.
"Register your interest to be the first in line to hear more about ABBA Voyage," it says.
And the whole affair has folks on the verge of jumping out of their skin.
One fan responded, "WE'RE READY,"
"Ready to add to the collection," said another, while many speculated that the announcement would be ABBA Voyage, a fresh new album.
One wrote: "How long will we have to wait for new music?" in response to a question about how long they'd have to wait for new tracks "Woohooooo! 39 years!"
Another person told the band: "I'll be transported back to 1978 when I was 16 years old and anticipating the release of the new album on cassette and listening to the new songs. I'm ecstatic beyond words."
While some speculate that ABBA is teasing a new album, others speculate that the announcement is related to the long-awaited hologram tour, which was first promised in 2016.
The band returned to the studio two years later, vowing to release two new songs in 2018.
I Still Have Faith In You and Don't Shut Me Down have been continually postponed, but they're now going to release five new songs as a thank you to fans for their patience.
Bjorn has stated that the new tracks would be published "definitely" this year.
"It's not a case anymore of it might happen, it will happen," he told The Herald Sun.
The holograms, dubbed Abba-tars, are said to resemble younger versions of the artists, who notably won the Eurovision Song Contest in 1974 with their song Waterloo.
The holograms are expected to be projected onto the stage in a specially designed theatre in east London, where fans will also be treated to a documentary chronicling the band's reunion.
Simon Fuller, the former manager of the Spice Girls, is behind the tour.
Bjorn previously told the BBC about how he came up with the idea for the band: "He came to Stockholm and presented us with the idea that we could create identical digital copies of ourselves at a specific age, and that these duplicates could then go on tour and sing our songs and lip-sync. I've only seen half of this project, but it's already mind-blowing."
The project's filming was alleged to have taken place in London's Ealing Studios last year.
