Activision is teasing out the announcement of what appears to be a new Guitar Hero game.

The video, above, shows a band psyching itself up and taking the stage to play a stadium concert.

The video closes with the strapline "It's about to get real" and ends with tomorrow's date, presumably when we can expect a full reveal.

In February, Kotaku reported that Activision was preparing to unveil a new game at E3 this year.

According to the publication's sources, the new Guitar Hero will adopt a "more realistic" approach than earlier entries in the series. It is due before the end of the year on PlayStation 4 and Xbox One, claimed the site.

That "more realistic" approach would certainly be in line with today's live action trailer and its strapline.

In March, rival franchise Rock Band also announced a comeback tour.

Mad Catz Interactive and Harmonix are partnering up to launch the title, which will release later this year for PlayStation 4 and Xbox One.

According to Harmonix, Rock Band 4 will focus on the features and gameplay that people love, and expand the franchise in innovative ways informed by how fans play and what they want.
