According to a missing slide from Harmonix senior designer's presentation at GDC, there will be a Lego Rock Band this year. The question is: Will it come with custom instruments like the Beatles' version?

Obviously—since the slide was not in the final presentation—Dan Teasdale didn't say a word about it, so we don't know. My hope that the instruments are—if not made with bricks—at least compatible with bricks. Imagine it: If their surfaces are covered with Lego-compatible studs, that would mean that any Lego and Rock Band fan would be able to customize them in any way they want using regular bricks.
