While Harmonix senior designer Dan Teasdale had intentions of talking about LEGO Rock Band during his GDC talk, "Dirty Deeds Done Dirt Cheap: Design Lessons Learned From Rock Band," that obviously didn't happen.

However, according to a PDF of an earlier version of the designer's session, the version "sent for speech approval rather than the version that I actually showed at GDC," according to Teasdale himself, LEGO Rock Band was planned to be announced prior to this year's Game Developers Conference. Teasdale's slides show that the game, rumored to be in development by LEGO video game development house Traveller's Tales, will hit in 2009.

One of Teasdale's slides — which, when shown at GDC did not feature the "Lego" title on the time line — shows the game may be expected to hit between the release of Rock Band Unplugged for the PSP and The Beatles: Rock Band.


A later slide, on the page following brief details on Rock Band Unplugged, a placeholder image for a "project to be announced before or at 9 AM Friday" is featured, which we're assuming to be LEGO Rock Band. Teasdale's notes on that slide read: "There's a project that I'll be talking about here, but it hasn't been announced yet. BUT - I will be showing it at GDC!"


As you can see, Teasdale also lists a few Guitar Hero titles schedule to be in development, including what may be the oft-rumored Guitar Hero: Van Halen title and what appears to be Guitar Hero: Band Hero. Whether Teasdale's in a position to know Activision's publishing schedule isn't perfectly clear. What is clear is that Activision has plenty of Guitar Hero exploitation planned for 2009.


We attended the Rock Band design session, but Teasdale made absolutely no mention of the LEGO branded version of the game. Promise — we would have told you.
