Rock Band developer Harmonix said that the absence of downloadable content on the Wii version of Rock Band is due to a lack of viable storage space, CVG reports.

The developer had confirmed that the Wii version of its rhythm party opus would not support downloadable content when the port was announced late last month.

"Come on Nintendo, we need a hard drive," said Rock Band design director Rob Kay. "That's what we want. The whole problem is there's nowhere to store it."

The Wii currently offers 512 megabytes of internal flash memory for storage, expandable via SD flash cards. Rock Band downloadable tracks range roughly between 20 and 40 megabytes per song.

"If the platform could do it, we'd jump on it," added Kay. "It's something that we championed to Nintendo, that we'd like to do it. Who knows what will happen down the line, I don't know what's coming down the line, but that's the reason there's no DLC in Wii Rock Band."
