Winter!: Prepare for holiday gaming!
Take Rock Band, get rid of everything but the voice, and throw in some very party-able features, maybe some refinement, and you have Lips. A very solid soundtrack (I guarantee there will be something for everyone), some nifty visuals (Mostly original music videos for the songs), and you have the recipe for one of the most fun music games out there.. if you can sing on key :)
