Harmonix has done an admirable job of keeping up a steady stream of new content for their Rock Band games across all platforms, with one of the stand-out areas for the developer has been the Rock Band Network. The Network was established as an area where aspiring artists could turn their own proprietary music into playable tracks for the Rock Band games, opening up a new stream of distribution for unsigned or little known bands. To date, the Network has been available for all three current platforms, Wii PS3 and 360. However in the most recent posting for new Rock Band DLC, the studio has announced that this week's Network's additions will be the last ones to come to the Nintendo Wii.
Citing as reasons for the move, Harmonix said the Wii's "smaller online install base, limited demand for releases so far and the significant amount of work it takes.... to process these additional tracks" mean that it's no longer cost effective to deliver to that platform. The company has stated that the normally added weekly DLC will continue uninterrupted.
There's no word as to whether or not this move is tied into Harmonix being sold by former parent company Viacom, although one has to think that the two factors must have something to do with one another. Besides, a quick scan of the Network's songs will show that, for the most part, the majority of songs that are added never get released on the Wii anyway. So all around it's a win-win: Harmonix gets to save some money, and Wii owners will likely never miss the content that they were either ignoring, or not being given access to anyway.
