Internet-leak time, folks: According to Harmonix senior designer Dan Teasdale's blog, Think Services, the company behind the Game Developers Conference, may have inadvertently revealed the existence of Lego Rock Band.
Teasdale says Think posted the wrong slides from his GDC presentation "Dirty Deeds Done Dirt Cheap: Design Lessons Learned From Rock Band" online. Think apparently posted an early draft of the presentation as opposed to the actual slides he showed at GDC. The online draft mentions Lego Rock Band. Judging from the slide, it's coming in 2009, between Rock Band Unplugged for the PSP and The Beatles: Rock Band.
That is all we know about the supposed title. Please don't consider this confirmed. Check out the "controversial" slide above. For all anyone knows, the part of the slide reading "Lego" could mean anything. It could be a joke. That's the way this kind of thing goes.
But the larger question is: If Lego Rock Band actually exists, is it even a good idea? Given Harmonix' stated goal of only including things in Rock Band that "feel like an authentic rock band experience," what does the Rock Band franchise gain out of being connected to Lego? For that matter, what does Lego gain out of being connected to Rock Band?
