Lego Rock Band accidentally confirmed

Harmonix designer Dan Teasdale's confirmed on his blog that Lego Rock Band was supposed to be announced at GDC. He's provided the slides to prove it.

There's a PDF there of an earlier version of the designer's GDC session - obviously, it didn't happen. Looks like Lego Rock Band was planned to be announced prior to this year's show.

Teasdale's slides show that the game will hit in 2009.

Told you.

Thanks, Kotaku.
