We've seen the rumors and heard the small leaks and we've always passed them off as some sort of joke, but it's really happening:  LEGO and Rock Band are joining forces for a family-friendly rhythm game coming this holiday season.  

From the entry on xbox.com comes these details about the game:

• Songs you know and love: Rock out to everything from current radio hits to past favorites the whole family will enjoy.
• LEGO-themed rock challenges: Play killer riffs to destroy a giant robot, summon a storm, and demolish a skyscraper using the power of rock!
• Enhanced customizer: Don't stop with your avatar, customize your whole entourage! Design the band, roadies, and manager just the way you want.
• Build fame LEGO-style: Collect LEGO bricks after each song to build cooler vehicles and move to new venues.
• LEGO rock den: Buy furniture, decorate the walls and customize your band's hang-out as you climb the ladder to rock success.
• Fun for everyone: Turn down the difficulty with an easier skill set option for budding musicians. 

In addition, five songs from the soundtrack have been announced.  No word on if these will be transferable to other Rock Band games.  Click "Read More" to see what songs you can look forward to.
