Despite appearing on a recent CV, Rock Band: Led Zeppelin isn't a game currently in the works, Harmonix has told VG247.
Nothing else is said on the profile besides a fleeting mention of the name.
Harmonix has told VG247 this afternoon that a Zep-based Rock Band title isn't in the works.
"As we've noted before, we're constantly in talks with all major artists and labels," it said in a statement.
"That said, Harmonix has never been in development on a Led Zeppelin game, though we'd obviously be thrilled to have them in Rock Band."
Harmonix has already released two band-flavoured Rock Band titles: Green Day and The Beatles, the latter the more significant of the two due to its importance. A Led Zeppelin game has been high on most-wanted lists from Rock Band fans.
