S'OK, PS3 owners. When McDonalds inked their little Rock Band advertising deal with Harmonix and MTV, they weren't just catering to the 360-owning demographic. They're thinking of you, too. So while the initial announcement may have come from Microsoft, MTV have since contacted us to let us know that the deal - which sees a range of songs on sale for 50% off - will apply for Rock Band on the PS3 as well.
