How likely is in your opinion a Zelda U port on the next Nintendo home console ?

Pretty much 100%. Nintendo consoles with a very strong launch title seem to do the best. The N64 had Super Mario 64 and the Wii had The Twilight Princess and those consoles had decent and amazing sales respectively. The Gamecube did not have strong launch titles and neither did the Wii U.
