The currently announced downloadable content for DJ Hero will run you $3 per mix. By comparison, Guitar Hero 5's individual tracks cost $2. When I asked last week, Activision refused to comment on whether this pricing scheme would be applied to future DJ Hero downloadable comment, but an IGN interview with developer FreeStyleGames suggests that's the plan.
"There's additional work in the creation process of the DLC," said commercial director Chris Lee, "[such as] licensing multiple pieces of content and bringing in a professional DJ to mix the tracks."
Lee successfully dodges a definitive answer, just as Activision did. It's still possible the pricing for DJ Hero will change, depending on how consumers react to the first wave of downloadable content, but the "additional work" answer that Lee provides suggests a $3-per-mix future for gamers.
