Chairman Scott Guthrie said that Harmonix has been looking into new technologies for the new game, including Natal.
"The Harmonix development team are working on what is effectively the next game, or Rock Band 3," he told MCV.
"We aren’t standing still. We will keep moving into new areas and look at new technologies that our platform holder partners are also developing, such as Project Natal from Microsoft.
"We’re working with them to pull some things togetherr. So it’s pretty exciting time for the future of our music game business."
Harmonix is currently working on Lego Rock Band and Beatles: Rock Band, both scheduled for release by the end of the year.
