Bizarre ‘Guitar Hero’ supergroup rocks out

We knew Rock Band was a hit, but apparently it was so successful that Guitar Hero, which came first, is now practically the same game. This "Risky Business" ad for GH4 features the two guitars, drum kit, and wireless mike that were formerly the sole province of Rock Band. We're curious to find out what adjustments Rock Band will make now. Hopefully, they'll involve in-game prompts that actually correspond to the songs being played. We were also surprised to find out that Michael Phelps, Kobe Bryant, Alex Rodriguez and Tony Hawk are very close friends. Closer than we're comfortable with, really.
