because for some reason alot of people rejected the anime style of WW, so sad cause it is one of the best games ever made it could boost wii u sales , if nintendo were not do dumb they would have had a full zelda title at launch or at the very least within a year
but the newer consoles are probably planning on a 10 years lifespan , since sony said they wanted a 10 year span for the ps3 but didnt quite make it
so if the wii u has another 6 or 7 or more years before a new console gen then that is the same lifespan as the wii ,post zelda wiiu lifespan will be at least 6 years ,at least as long as the lifespan of the wii ,price drops and a zelda release should be able to boost sales and get some more 3rd party support before it is all over , hopefully because the next gen may not have any physical media , this could be the last gen of modable consoles sadly
