Released back in October 2009, Rock Band iOS was co-developed by EA Montreal and Harmonix, with publishing handled by Electronic Arts and MTV Games. Two years later, parent-company Viacom would sell-off Harmonix, and MTV Games would cease to exist. Harmonix has since continued on as an independent developer, finding massive success in Dance Central, but a supremely weird pop-up started presenting itself in Rock Band iOS yesterday. A pop-up which appears to claim the game has an expiration date.
