A job posting by Time Warner states that the company has actually partnered with Nintendo and other established organisations to launch HBO & Max Go in the future. Nintendo hasn’t announced the partnership, so it’s likely that they’re saving the announcement for E3. The company was previously reported to be in negotiations with various media partners for Wii U.
“The Partner Manager position is responsible for the day-to-day relationship and ongoing marketing activities with several key Mobile, Tablet, Connected TV and Game Console digital partners for HBO GO and MAX GO. Partners include Apple, Amazon, Google, Microsoft, Sony, Nintendo, Samsung, Roku, as well as any new partners that will launch HBO/MAX GO in the future.”
