A VG247 source has claimed Traveller's Tales is working on a Lego version of Rock Band for EA.
Our chatterer assured us the information was "100 percent correct".
UK developer TT Games confirmed in a Radio One interview with EGTV's Johnny Minkley last night that a Lego game is to be released this year, but refused to confirm its identity.
Minkley speculated the title was a second Indiana Jones game during the show.
Traveller's Tales was rumoured recently to be working on Lego Harry Potter, talk Warner slapped with a swift "no comment".
A Lego Potter game would have to be a collaboration with EA, as the publisher owns game rights to the Hogwarts hyper-franchise.
Traveller's Tales - which is owned by Warner Bros - has yet to confirm future projects, having released Lego Indiana Jones and Lego Batman in 2008.
EA US was unavailable for comment at the time of writing.
