It would seem that the Wii is getting an anime rental service of sorts this December in Japan. Mainly focusing on children's content, the episodes will range from 100-400 Wii Points while the WiiWare itself will cost 500 points. The episodes will be in MP4 format and will be viewable for 72 hours after purchase. As of yet it is unknown if this will ever release outside of Japan. Thanks for reading! Check out the original story here. And additional resource here, but fyi, it's in Japanese.
