Computerandvideogames.com recently interviewed Rob Kay, design director at Harmonix, and the topic of Rock Band for Wii came up.
Since the announcement, the internets have been in a perpetual whiny state about the lack of downloadable content for the Wii version of the game. Kay responded with some choice words, making it clear that they want to be able to provide Wii users with DLC but can't due to Nintendo's choices.
Come on Nintendo, we need a hard drive. That's what we want. The whole problem is there's nowhere to store it. If the platform could do it, we'd jump on it. 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.
CVG will have more of their interview with Rob Kay later this week.
