According to a report on UGO's Wii channel, Nintendo may use EA's Origin service with its upcoming Wii U console. According to an anonymous tip from within EA, the company is supposedly working with Nintendo on a deal related to the Origin digital distribution platform. The source claims that EA and Nintendo are in talks to use Origin as Nintendo’s primary hosting platform for game distribution online.
The source also claims that Valve has been talking with Nintendo, but the impression they give is that EA is being extra aggressive in sealing the deal.
Both EA and Nintendo have not publicly commented on this story - and even if they did chances are their response would be "no comment" or "we don't comment on rumors." For now consider it an interesting rumor.
