In recent scan of a magazine, the scans were translated. The scans said that Super Smash Bros. Brawl will get a channel called Super Smash Bros. Brawl New Challenger. This channel would allow you to download new characters, items, stages, music, stickers and more! These additional downloads will not be free. You will have to use Wii points to download the material. No other details have been released. If you'd like to take a look at the scan, then please visit the link below.

Nintendo will reveal this channel soon, as rumored.

I believe that this rumor may be true. It's just an excellent idea. They could add more stuff to Brawl that will make it awesome. For instance, maybe Capcom will change there mind and give the right to put Megaman in Brawl. Nintendo can then make a moveset and then put it up for download. This channel will be very useful.
